Outcomes of cataract surgery in monocular patients

PURPOSE: To determine the best corrected visual acuity (BCVA) outcomes and surgical complications in a consecutive series of functionally monocular patients who had phacoemulsification and intraocular lens (IOL) implantation. SETTING: University-based referral practice, Los Angeles, California, USA. METHODS: The medical records of 93 monocular patients who had phacoemulsification and IOL implantation between December 1991 and February 1999 were reviewed. Patients were considered to be monocular if Snellen BCVA in their fellow eye (the eye not having surgery) was worse than 20/200. Recorded were demographic information, anesthesia method, additional surgery, IOL model, preoperative and postoperative BCVA, reason for poor vision in the unoperated eye, co-morbidities in the operated eye, intraoperative and postoperative complications, length of follow-up, and postoperative procedures. RESULTS: Mean patient age was 72 years and mean follow-up, 6 months. Thirteen patients (14%) were monocular from complications of surgery. Eighty patients (86%) were monocular because of medical eye conditions. Ocular co-morbidities were present in 75% of eyes having surgery. Preoperative median BCVA was 20/60. Median BCVA was 20/30 by the final scheduled follow-up examination and 20/25 by the final follow-up examination. Thirty-seven percent of eyes were correctable to 20/20 or better, and 67% were correctable to 20/40 or better. Two eyes lost BCVA by the final scheduled postoperative examination, and 3 eyes lost BCVA by the final follow-up examination. Final BCVA of worse than 20/40 was always related to preexisting macular or optic-nerve pathology. There were 16 intraoperative or early postoperative complications. The most common (3 eyes) was posterior capsule plaque that could not be removed by capsule polishing. Twenty eyes (22%) had subsequent surgical procedures, the most common being laser posterior capsulotomy. No patient who was monocular from surgical complications had similar problems with second-eye cataract surgery. CONCLUSIONS: Best corrected visual acuity, the standard measure of efficacy in cataract surgery, improved a median of 3 to 4 Snellen lines. The safety of the procedure, as evidenced by the small number of patients who lost BCVA or experienced surgical complications, was satisfactory. Functionally monocular patients are likely to have ocular co-morbidities, some of which may limit the final visual outcome of surgery.     

Long-term results of combined 1-way phacoemulsification, intraocular lens implantation, and trabeculectomy

PURPOSE: To analyze the results of 1-way phacoemulsification and posterior chamber intraocular lens (IOL) implantation combined with trabeculectomy. SETTING: Department of Ophthalmology and Neurosurgery, University of Siena, Siena, Italy. METHODS: This retrospective study comprised 42 eyes of 36 patients with glaucoma and cataract who had phacoemulsification with posterior chamber IOL implantation combined with trabeculectomy. The mean follow-up of 28.24 months +/- 10.99 (SD) (range 11 to 52 months) included measurement of intraocular pressure (IOP), visual acuity, visual field, endothelial cell loss, and notation of complications. RESULTS: There was a statistically significant postoperative improvement in visual acuity (P < .001). Mean preoperative best corrected visual acuity (BCVA) was 20/200 (range 20/30 to hand movements). Mean 1 year postoperative BCVA was 20/30 (range 20/20 to 20/60). The preoperative mean IOP of 24.06 mm Hg decreased to 15.36 mm Hg at 1 year (P < .001). All 42 eyes had a postoperative IOP of less than 21.00 mm Hg. Mean central cornea endothelial cell density preoperatively was 2238 +/- 396 cells/mm2 (range 1697 to 2906 cells/mm2) and postoperatively, 2005 +/- 397 cells/mm2 (range 1302 to 2801 cells/mm2). Early postoperative complications consisted of a choroidal detachment in 2 patients (4.76%). Three and 4 days after surgery, respectively, 2 patients (4.76%) had surgery to remove viscoelastic substance under the IOL. Late complications included posterior synechias in 3 eyes (7.14%). One year after surgery, because of a significant decrease in vision, a neodymium:YAG laser posterior capsulotomy was necessary in 2 eyes, 1 with an acrylic IOL (3.70%) and 1 with a silicone lens (9.09%). CONCLUSION: Combined phacoemulsification, posterior chamber IOL implantation, and trabeculectomy was safe and effective in patients with coexisting glaucoma and cataract.     

Long‐term results of bilateral congenital cataract treated with early cataract surgery,aphakic glasses and secondary IOL implantation

Purpose: To evaluate the long‐term visual outcome after early surgery of bilateral dense congenital cataracts, aphakic correction with glasses and secondary intraocular lens (IOL) implantation around 2 years of age. Methods: The medical records of paediatric patients who underwent cataract extraction, aphakic correction and secondary IOL implantation from 1993 to 2004 at Seoul National University Children’s Hospital were reviewed retrospectively. Age at secondary IOL implantation, axial length (AL), best corrected visual acuity (BCVA), refractive error, ocular alignment, stereopsis, and postoperative ocular complications were recorded. Results: Thirty‐seven paediatric bilateral pseudophakic patients were identified with a mean follow‐up period of 81.4 months. Best corrected visual acuity of 20/40 or better were attained in 44.0% of eyes, and the median BCVA was 20/50. Preoperative factors associated with poor visual prognosis included cataract surgery after 8 weeks of age, interocular AL difference of 0.5 mm or more, and glaucoma. Amblyopic eyes showed more myopic change compared to fellow eyes. Good or moderate binocular function was achieved in 18.9% of all patients. Incidences of strabismus, glaucoma, posterior capsular opacity formation were 46.0%, 32.4% and 4.0%, respectively. Conclusion: Good postoperative BCVA and binocular function were achieved in most healthy children with bilateral dense congenital cataract and no posterior segment pathology. Early cataract surgery, aphakic correction with glasses and secondary IOL implantation around 2 years of age appears to be appropriate methods.

Combined lens and vitreoretinal surgery in patients with traumatic cataract and intraocular foreign body

AIM: To analyze the postoperative anatomical and functional outcomes as well as complications after combined phacoemul- sification, pars plana vitrectomy (PPV), removal of the intraocular foreign body (IOFB) and intraocular lens (IOL) implantation in patients with traumatic cataract and intraocular foreign body. METHODS: Medical records of 13 patients(13 eyes) with traumatic cataract and IOFB who had undergone combined phacoemulsification, PPV, foreign body extraction and IOL implantation were retrospectively analyzed. The postoperative follow-up ranged from 2 to 12 months. The main measure- ments of outcomes were the extraction success of cataract and intraocular foreign body, intraoperative and postoperative complications and the final best corrected visual acuity (BCVA). ·RESULTS: The mean age of 13 patients(10 male, 3 female )was 36.8 years (range: 17-65 years). All eight IOFBs were removed. Four intraocular lenses were implanted after vitrectomy intraoperatively. In 5 cases, intraocular lenses were implanted during the second operation. Intraocular lenses were not implanted in 4 cases. BCVA at last ranged from 0.8 to hand movement. BCVA was 0.5 or better in four eyes, 0.1 to 0.4 in five eyes, less than 0.1 in four eyes. Intraoperative complications were encountered in 3 patients. They had vitreous hemorrhage. Postoperative complications were encounter- ed in 2 patients. They had retinal detachment. The reoperations of the two patients were successful. CONCLUSION: The combined phacoemulsification, PPV, removal of IOFB and IOL implantation is safe and effective for patients with traumatic cataract and intraocular foreign body. The visual outcome depended primarily on the corneal or scleral wound and underlying posterior segment pathology and sites.

Primary implantation of posterior chamber lenses after traumatic cataract peneration

PURPOSE: To analyze the postoperative outcome and complication rate after phacoemulsification, lens aspiration or lensectomy with primary intraocular lens (IOL) implantation after traumatic cataract penetration. METHODS: We retrospectively reviewed the data of 15 patients who were admitted to our hospital from 1997 to 2001 because of traumatic cataract with corneal laceration with and without intraocular foreign body (IOFB). In all patients phacoemulsification, lens aspiration or lensectomy and primary IOL implantation were performed. Removal of IOFB was performed in 6 patients. RESULTS: The mean follow-up was 19.6 months, 8 eyes (53%) achieved a final visual acuity of 20/40 or better and 12 eyes achieved 20/100 or better final visual acuity. One patient (final visual acuity=1/40) had an additional macular pathology. Due to irregular astigmatism two patients achieved a final vision of less than 20/100. Major causes of limited visual acuity were central corneal scars and in one patient a photopic maculopathy. Four eyes (25%) developed secondary cataract and underwent YAG laser capsulotomy. In one patient PVR retinal detachment had to be treated by pars-plana vitrectomy with silicone oil tamponade. CONCLUSIONS: Primary implantation of posterior chamber lenses after penetrating ocular trauma is associated with a favourable visual outcome and a low rate of postoperative complications.

Modified capsular tension ring for patients with congenital loss of zonular support

PURPOSE: To evaluate the results of implantation of a modified capsular tension ring (MCTR) and a posterior chamber intraocular lens (PC IOL) in patients with congenitally subluxated crystalline lenses. SETTING: Cincinnati Eye Institute, Cincinnati, Ohio, USA. METHODS: Ninety eyes of 57 patients with congenital loss of zonular support (Weill-Marchesani syndrome, idiopathic ectopia lentis, and Marfan's syndrome) had phacoemulsification with PC IOL and MCTR implantation. The preoperative examination included best corrected visual acuity (BCVA) and the presence or absence of phacodonesis, lens decentration, and vitreous prolapse. The postoperative evaluation included BCVA and the presence or absence of pseudophacodonesis, PC IOL centration, and posterior capsule opacification (PCO). RESULTS: At the last postoperative examination, the BCVA was 20/40 or better in 80 eyes (88.9%); 1 eye (1.1%) lost 1 line of acuity. Preoperatively, 18 eyes (20%) had phacodonesis; 1 eye had postoperative pseudophacodonesis. Decentration before surgery was present in 86 eyes (95.6%); 6 eyes (6.7%) developed late symptomatic PC IOL decentration a median of 17.84 months +/- 10.73 (SD) after surgery. Other complications were increased intraocular pressure (2.2%), persistent iritis (3.3%), broken suture (10.0%), retinal detachment (1.1%), and PCO (20.0%). CONCLUSIONS: Use of the MCTR resulted in centration of the capsular bag and PC IOL in 90 eyes with congenitally subluxated crystalline lenses. Fixation of a 9-0 polypropylene suture is recommended to decrease the risk for late suture breakage.

Outcome of simultaneous phakic implantable contact lens removal with cataract extraction and pseudophakic intraocular lens implantation

PURPOSE: To assess the outcome of simultaneous implantable contact lens (ICL) removal and cataract extraction with pseudophakic intraocular lens (IOL) implantation. SETTING: CODET Aris Vision Institute, Tijuana, Mexico. METHODS: This retrospective noncomparative interventional case series evaluated 14 eyes of 12 patients with ICL implantations who developed a cataract and simultaneously had ICL removal and cataract extraction with IOL implantation. The follow-up time was at least 6 months (range 6 to 24 months). Visual acuity (logMAR), manifest refraction, intraocular pressure, and adverse events were recorded. RESULTS: Of the 12 patients (14 eyes), 10 patients (12 eyes) had ICL surgery to correct high myopia and 2 patients (2 eyes), to correct hyperopia. The mean uncorrected visual acuity after ICL implantation (before cataract development), before cataract surgery, and after cataract surgery were 0.48 +/- 0.32, 0.83 +/- 0.34, and 0.40 +/- 0.27, respectively. The mean best corrected visual acuity (BCVA) before ICL implantation, after ICL implantation, and after cataract surgery were 0.31 +/- 0.21, 0.28 +/- 0.19, and 0.27 +/- 0.21, respectively. The mean final manifest spherical equivalent was 0.30 diopters (D) +/- 1.07 (SD) (range +2.38 to 2.0 D). Ten eyes (71.4%) were within +/-1.0 D of the calculated target. One eye had a tear in the posterior capsule with vitreous loss during cataract surgery. No other intraoperative, perioperative, or postoperative complications were observed. No loss of BCVA was recorded at the last postoperative visit. CONCLUSIONS: Lens opacities and cataract formation are a potential complication of ICL surgery. The removal of the ICL and the cataract with IOL implantation was found to be safe, with predictable refractive results.     

Extracapsular cataract extraction and posterior chamber intraocular lens implantation in uveitis patients.

PURPOSE: Intraocular lens implantation in uveitis patients has been a controversial issue. The purpose of this study is to evaluate the visual and surgical outcomes of extracapsular cataract extraction (ECCE) and posterior chamber intraocular lens (PC IOL) implantation in a diverse group of uveitis patients. PATIENTS AND METHODS: The results of 39 cases of ECCE and PC IOL implantation in 30 patients with uveitis were retrospectively analyzed. Five patients (six eyes) had pars plana vitrectomies combined with ECCE and PC IOL implantation. Patient age ranged from 26 to 71 years (average, 53.0 years). Specific uveitic syndromes were determined for 22 patients (73.3%). The postoperative follow-up period ranged from 6 to 43 months (average, 20.3 months). RESULTS: Visual acuity improved postoperatively in 38 eyes (97.4%), and this improvement ranged from 1 to 11 Snellen lines (average, 7.5 Snellen lines). Visual acuity improved postoperatively to 20/40 or better in 32 eyes (82%). Seven eyes had visual acuity worse than 20/40, which was attributed to posterior segment abnormalities after ECCE and PC IOL implantation. Uveitis recurred in 20 eyes (51.3%), and postoperative cystoid macular edema (CME) was observed in 18 eyes (46.2%). In all cases, the recurrent uveitis and CME improved or resolved with corticosteroid therapy. CONCLUSION: These results suggest selected uveitis patients can have improved vision without unacceptable risk for 1 to 3 years after ECCE and PC IOL implantation.

目的利用前节OCT检查证实Bigbag人工晶状体在囊袋中的稳定性,探讨Bigbag人工晶状体在高度近视并发白内障的临床应用效果。方法 90例(169眼)高度近视并发性白内障患者超声乳化吸除术后,45例86眼(研究组)行Bigbag人工晶状体植入术,45例83眼(对照组)行AMO AR40e人工晶状体植入术,观察术中及术后并发症、眼压、术后最佳矫正视力(bestcorrected visual acuity,BCVA)、裸眼视力和屈光状态、角膜内皮细胞计数、后囊膜皱褶。前节OCT检查术前及术后前房深度(an-terior chamber depth,ACD)。术后随访1～3个月。结果术中无后囊膜破裂等手术并发症。前节OCT检查ACD结果显示:研究组术前、术后3d、1个月平均ACD分别为(3.54±0.24)mm、(5.27±0.21)mm、(5.25±0.18)mm;对照组平均ACD分别为(3.61±0.16)mm、(4.11±0.35)mm、(3.91±0.24)mm。两组间术前ACD、术后两组内不同时间ACD比较差异均无统计学意义(均为P>0.05),术后两组间比较差异均有统计学意义(均为P<0.05)。术后1个月研究组BCVA<0.1者4眼,0.1～0.4(包括0.4)者18眼,0.4～0.8者57眼,>0.8者7眼,术后1个月、3个月BCVA、裸眼视力与对照组相比差异均无统计学意义(均为P>0.05)。两组术后3个月实际屈光度数与术前预留屈光度数差值≤±1.0D者研究组54眼(62.79%)、对照组40眼(48.19%),差异有统计学意义(P<0.05)。研究组1眼(1.16%)、对照组5眼(6.02%)出现后囊膜混浊及皱褶。研究组术后未见严重并发症,对照组2眼(2.41%)术后3周左右发现视网膜脱离。结论 Bigbag人工晶状体植入后稳定性好;可获得与其他人工晶状体无差异的术后视力;对后囊膜有稳定支撑作用,降低了后囊膜皱褶的发生率;对高度近视并发性白内障患者安全、有效。     

Visual outcomes after vitreous loss during cataract surgery performed by residents

PURPOSE: To evaluate the visual outcomes after vitreous loss during cataract surgery performed by residents. SETTING: Parkland Memorial Hospital, Dallas, Texas, USA. METHODS: A retrospective chart review of all patients who had cataract extraction complicated by vitreous loss from 1997 through 1999 was conducted. All surgery was performed by third-year ophthalmology residents. RESULTS: In 1400 cataract surgeries, 63 cases of vitreous loss (rate 4.5%) were identified. One case had less than 1 month of follow-up and was excluded from further analysis. Of the 62 remaining cases, 53 had phacoemulsification, 7 extracapsular cataract extraction (ECCE), 1 phacoemulsification converted to ECCE, and 1 intracapsular cataract extraction. Thirty-two eyes had a sulcus-fixated posterior chamber intraocular lens (PC IOL) implanted, 20 an anterior chamber IOL, and 7 a PC IOL in the capsular bag; 3 eyes were left aphakic at the time of initial surgery. Overall, 77% of patients had a postoperative best corrected visual acuity (BCVA) of 20/40 or better. Of the 14 patients who did not have a BCVA of 20/40 or better, 9 had preexisting ocular pathology affecting vision. If these 9 patients are excluded, 91% of patients with vitreous loss had a BCVA of 20/40 or better. Six patients (10%) developed clinical cystoid macular edema. No patient with vitreous loss developed a retinal detachment or endophthalmitis. CONCLUSIONS: Good visual acuity can be achieved after resident cataract surgery complicated by vitreous loss. The rate of vitreous loss in this study is consistent with that in previous reports of resident cataract surgery in the literature.

Combined surgery and sequential surgery comprising phacoemulsification,pars plana vitrectomy,and intraocular lens implantation: comparison of clinical outcomes

PURPOSE: To evaluate the effectiveness and safety of combined phacoemulsification, pars plana vitrectomy (PPV), and intraocular lens (IOL) implantation in diabetic and nondiabetic patients and compare the clinical results with those of sequential surgery. SETTING: Seoul National University College of Medicine, Seoul, South Korea. METHODS: The results of combined phacoemulsification, PPV, and IOL implantation in 52 patients (52 eyes) were retrospectively analyzed. The main outcome measures were preoperative and postoperative best corrected visual acuity (BCVA), postoperative BCVA of 20/40 or better, and intraoperative and postoperative complications. Combined surgery and sequential surgery were also compared using the same outcome measures. RESULTS: Postoperatively, the BCVA was better in 44 eyes (84.6%); 12 eyes (23.1%) achieved a BCVA of 20/40 or better. Postoperative complications consisted of a transient intraocular pressure increase in 29 eyes (55.8%), hyphema in 10 (19.2%), neovascular glaucoma in 8 (15.4%), anterior chamber fibrin exudation in 7 (13.5%), vitreous hemorrhage in 7 (13.5%), retinal detachment in 3 (5.8%), and posterior capsule opacification in 1 (1.9%). In the diabetic patients, postoperative visual outcomes between the combined-surgery group and the sequential-surgery group were not significantly different; however, neovascular glaucoma occurred only in the combined-surgery group. Other complications were not different between the combined-surgery group and the sequential-surgery group. In the nondiabetic patients, the postoperative visual outcomes and complications between the 2 groups were not significantly different. CONCLUSIONS: Combined phacoemulsification, PPV, and IOL implantation was safe and effective in selected patients, with the clinical outcomes comparable to those of sequential surgery.
