Clinical aspects, follow-up and results of cataract extraction in uveitis]

Over a 5-year period, a consecutive series of 52 eyes in 46 patients with uveitis underwent extracapsular cataract extraction. Twenty-eight of these cases received a posterior chamber intraocular lens (IOL). During an average follow-up of 25 months (range 7 to 58 months) 71% of eyes receiving an IOL achieved postoperatively a visual acuity of 0.5 or better; 54% of aphakic eyes reached this level. Persistent cystoid macular edema limited the visual improvement to 20/200 in 6 patients; none of the patients developed cystoid macular edema postoperatively on clinical observation. Intraocular hypertension occurred postoperatively in 12 eyes, but was limited to a 4-week postoperative period in 9 cases. YAG laser capsulotomy was performed in 2 eyes with opacification of the posterior lens capsule without any further complications. The results suggest that uveitis patients benefit from cataract extraction and in selected cases can tolerate IOL implantation without major complications.

Transsclerally fixated intraocular lenses in children

BACKGROUND AND OBJECTIVE: To evaluate the visual outcome and complications of transsclerally fixated intraocular lenses (IOLs) in children without sufficient capsular support. PATIENTS AND METHODS: Twenty-one aphakic eyes of 18 children (13 boys and 5 girls) who underwent secondary transscleral IOL fixation were evaluated retrospectively. Ten eyes with aphakia after infantile cataract surgery, 7 aphakic eyes following traumatic cataract surgery, and 4 eyes after ectopia lentis surgery received secondary transscleral posterior chamber IOL fixation because of by insufficient posterior capsular support. Visual outcomes and postoperative complications were recorded. RESULTS: After a mean follow up of 22.5 months (range, 12 to 36 months), visual improvement of more than 2 Snellen lines was observed in 9 eyes (42.8 %). Preoperative visual acuity could not be assessed in 7 eyes (33.3%) because of associated neurological and developmental disorders. One eye (4.7%) lost 2 Snellen lines of the best corrected visual acuity because of concurrent endophthalmitis and retinal detachment. Pupillary distortion, transient pupillary membrane, pupillary capture as well as strabismus and anterior uveitis, were the most common complications. Endophthalmitis and retinal detachment were the most severe postoperative complications. CONCLUSION: Transsclerally fixated IOL implantation may be visually rewarding in well selected pediatric cases, but the potential complications would suggest extreme caution in its consideration. Until long-term studies are published, it is difficult to recommend implantation unless it is deemed impossible to provide adequate rehabilitation by other means such as contact lenses or aphakic spectacles.

Scleral fixated (sutured) posterior chamber intraocular lens implantation in children.

BACKGROUND: Optical rehabilitation of unilateral aphakia in eyes with no capsular support is problematic in pediatric patients who cannot tolerate contact lenses. Possible options include a unilateral aphakic spectacle, an anterior chamber intraocular lens (IOL), or a scleral fixated posterior chamber IOL. Of these choices the posterior chamber IOL is the most physiologic. Experience in adults shows increased complications with this technique. OBJECTIVE: The objective of this study was to report the short-term results and complications of unilateral scleral fixated posterior chamber IOLs in the pediatric population. METHODS: All patients with scleral fixated lenses younger than 16 years were retrospectively reviewed. Nine patients aged 12 months to 15 years underwent unilateral scleral fixated posterior chamber lens implantation using buried polypropylene fixation sutures. Follow-up averaged 24 months. RESULTS: Postoperative visual acuity improved in all patients. Refractive goals were achieved in all but 1 patient. Complications included elevated intraocular pressure controlled with medications (1 patient), anterior uveitis (1 patient), and mild IOL decentration (1 patient). CONCLUSIONS: Although short-term visual results appear encouraging, this procedure is technically more difficult and has an increased incidence of postoperative complications when compared with secondary sulcus-fixated IOLs supported by capsular remnants. Caution should be exercised when recommending this procedure for pediatric patients because long-term risks are unknown.     

Cataract surgery in children with chronic uveitis

OBJECTIVE: To evaluate the visual outcome of cataract surgery in children's eyes with chronic uveitis and the feasibility of intraocular lens (IOL) implantation in these cases. DESIGN: Retrospective noncomparative case series. PARTICIPANTS: Seventeen children (20 eyes) with chronic uveitis, dense cataract, and a preoperative visual acuity of 6/120 or less with follow-up of 5 years after the initial cataract surgery. METHODS: In 10 eyes of 10 children (five with juvenile rheumatoid arthritis [JRA] and five with non-JRA-associated uveitis) with uniocular or markedly unequal binocular disease, surgery was carried out through the limbus and a posterior chamber IOL was implanted. In seven children (10 eyes), three with JRA and four with non-JRA-associated disease, a pars plana approach was used, and contact lenses or glasses (for the bilateral cases) were prescribed. RESULTS: The postoperative course and immediate restored visual acuities were similar whether an IOL was implanted or not. One month after the surgery, visual acuity improved in all operated eyes. After monocular surgery, in the younger children, contact lenses were poorly tolerated and their use discontinued. These aphakic eyes remained with low vision, developing strabismus on longer follow-up. Children with JRA-associated uveitis were younger, demonstrated an active intraocular inflammation for an extended period after surgery, and tended to have secondary membranes develop, necessitating a second surgical intervention. Five years after the initial surgery, only two of nine eyes (22%) in the JRA group (one aphakic of a bilaterally affected child and one pseudophakic in a child undergoing cataract surgery in one eye) retained a visual acuity of 6/9 and 6/6, respectively. In the other seven eyes, the visual acuity was 6/60 in one pseudophakic eye and 6/240 or less in six eyes (three aphakic and three pseudophakic). In children with non-JRA-associated uveitis, 6 (four aphakic in two patients bilaterally affected and two pseudophakic) of 11 eyes (54.5%) retained a vision of 6/12 or better. CONCLUSIONS: Cataract surgery in children's eyes with uveitis may be beneficial. IOL implantation seems preferable to correction with contact lenses in young children needing surgery in one eye. In children with JRA-associated uveitis, the final visual results remain guarded because of irreversible amblyopia and a more complicated postoperative course. For these cases, a modified management approach and a better surgical technique are needed.     

Secondary intraocular lens implantation in aphakia.

We retrospectively studied secondary intraocular lens (IOL) implantation in 165 aphakic patients (162 eyes) from May 1983 to August 1989. Seventy-five eyes (46.3%) had secondary IOL implantation; these included seven cases of trans-sulcus scleral fixation of the posterior chamber lens. The remaining 87 eyes could not have secondary IOL implantation because of the ocular conditions. The most common reason for secondary implantation was to relieve the discomfort caused by spectacles or contact lenses (56.2%). An anterior chamber lens was used in 43 eyes (57.3%) and a posterior chamber lens in 32 eyes (42.7%). Final postoperative visual acuity of 20/40 or better was achieved in 92.0% of the eyes with posterior chamber lenses, in 71.4% of the eyes with anterior chamber lenses, and in 57.1% of the eyes with scleral-fixated posterior chamber lenses. Endothelial cell loss was greater in the eyes with anterior chamber lenses than in the eyes with posterior chamber lenses. Of the cases that could be followed, 83.3% showed endothelial cell loss of less than 30% at six months postoperatively. Postoperative complications such as cystoid macular edema, persistent fibrinous membrane formation, and neovascular glaucoma occurred in only ten (13.3%) of the 75 eyes that had secondary implantation. These complications occurred more frequently in eyes that had anterior chamber lenses with anterior vitrectomy. There were no noticeable complications in the eyes that had trans-sulcus scleral fixation of posterior chamber lenses. Updrawn pupil, prolapsed vitreous, and peripheral anterior synechia were common conditions preventing secondary IOL implantation.

结论：IOL睫状沟缝线固定术是治疗无晶状体眼安全有效的方法,但应重视相关并发症。     

Outcomes of phacoemulsification and in-the-bag intraocular lens implantation in Fuchs' heterochromic iridocyclitis

PURPOSE: To evaluate the visual outcomes and complications of phacoemulsification (PE) and posterior chamber intraocular lens implantation, (PC IOL) in patients with Fuchs heterochromic iridocyclitis (FHIC). SETTING: Private clinic and an academic hospital. METHODS: In this noncomparative interventional case series, existing data for 41 eyes of 40 consecutive patients clinically diagnosed with FHIC and cataract were studied retrospectively. Scleral tunnel PE and in-the-bag IOL implantation were performed in all cases. Preoperative and postoperative visual acuities and intraoperative and postoperative complications were evaluated. RESULTS: Twenty-four male and 16 female patients aged 12 years to 70 (SD) (mean 35 +/- 12 years) were operated on and followed for 17.8 +/- 8.7 months. Preoperatively, best corrected visual acuity (BCVA) was less than 20/40 in all patients, which improved to 20/40 or better after surgery. Twenty-two eyes (53.6%) achieved BCVA of 20/20. The major cause of postoperative visual acuity less than 20/20 was vitreous haze. There were no major intraoperative complications. Postoperatively, mild anterior chamber fibrin reaction occurred in 4 patients (9.7%), IOL deposits occurred in 11 eyes (26.8%), and decentration was observed in 1 eye. During follow-up, 6 eyes (14.6%) developed posterior capsule opacification requiring a neodymium:YAG (Nd:YAG) laser capsulotomy. There was 1 case of clinical cystoid macular edema that resolved with medication. There were no cases of posterior synechias, postoperative glaucoma, or retinal detachment. CONCLUSION: Phacoemulsification with PC IOL implantation is a safe procedure with good visual outcomes in patients with FHIC and cataract.

Comparison of Artisan iris-claw intraocular lens implantation and posterior chamber intraocular lens sulcus fixation for aphakic eyes

AIM: To compare the efficacy and complications of Artisan iris-claw intraocular lens (IOL) implantation and posterior chamber IOL sulcus fixation for the treatment of aphakic eyes without capsular support after vitrectomy.METHODS:A prospective study of 45 cases was conducted. Forty-five eyes without sufficient lens capsule support following pars plana vitrectomy (PPV) combined lens extraction were divided into two groups. Group A:25 eyes received Artisan iris-claw IOL implantation. Group B:20 eyes received posterior chamber IOL sulcus fixation. The corrected distance visual acuity (CDVA) and intraocular pressure (IOP), corneal endothelial cell loss rate, surgical time and complications were compared between the two groups. Pigment changes of trabecular meshwork and anterior chamber depths were measured at each time point in Artisan group.RESULTS:The mean surgical time of Artisan group was significantly shorter (P<0.05). No statistically significant difference in endothelial cell loss rate was noted between two groups at any time point (P>0.05). CDVA of Artian group was better than that of the sulcus fixation group 1d after surgery (P<0.05) and there was no statistically significant difference 1 and 3mo after surgery (P>0.05). Mean IOP showed no significant differences between groups before and after surgery. The postoperative complications of Artisan group were anterior uveitis, iris depigmentation, pupillary distortion and spontaneous lens dislocation. The complications of sulcus fixation group include choroidal detachment, intraocular haemorrhage, tilt of IOL optic part and retinal detachment.CONCLUSION:Secondary Artisan IOL implantation can be performed less invasively and in a shorter surgical time period with earlier visual recovery after surgery compared to transscleral suturing fixation of an IOL. This technique is an effective and safe procedure. It is a promising option for the treatment of aphakic eyes without capsular support after vitrectomy.     

Clinical results of phacoemulsification in patients with uveitis.

BACKGROUND AND OBJECTIVE: To evaluate the results of phacoemulsification and posterior chamber intraocular lens (IOL) implantation in patients with uveitis. PATIENTS AND METHODS: Review of records of 37 eyes of 31 patients with uveitis (14 men and 17 women; mean age, 49.8 years; age range, 26 to 71 years) who underwent phacoemulsification with IOL implantation. The data recorded were age, gender, IOL type, treatment modalities, final visual outcome, and complications. RESULTS: Panuveitis, anterior uveitis, posterior uveitis, and intermediate uveitis were detected in 16 (51.6%), 9 (29.0%), 5 (16.1%), and 1 (3.3%) of the patients, respectively. At 6 months postoperatively, 32 (86.5%) eyes had achieved a best-corrected visual acuity of 20/40 or better, and 22 (59.5%) eyes had a visual acuity of 20/20. Five (13.5%) eyes showed limited improvement in postoperative visual acuity due to posterior segment problems. Postoperative recurrence of inflammation occurred in 12 eyes (32.4%) of 10 patients and was treated and controlled with medical therapy. CONCLUSION: When inflammation in uveitic eyes is under complete control, phacoemulsification and implantation of a foldable acrylic IOL in the posterior chamber is safe, effective, and tolerated well. To minimize vision-limiting complications, these patients must be observed closely after surgery, and must be treated aggressively if the inflammation recurs.     

Original three-point fixation technique for sutured posterior chamber intraocular lens

PURPOSE AND METHODS: In order to avoid the complications associated with posterior chamber intraocular lens (IOL) scleral fixation, the authors have developed an original surgical technique by which the IOL is secured at the ciliary sulcus by suturing the haptics to the sclera in three points (at the 3, 5 and 9 o'clock positions). This technique was utilized for secondary IOL implantation in 21 aphakic eyes. The mean follow-up was 18 months, range 6-28 months. RESULTS: All eyes that underwent secondary implants had equal or better visual acuity postoperatively; none developed serious intra- or postoperative complications. No tilt or decentration of the IOL was observed postoperatively. DISCUSSION: The technique described appeared easy to perform and produced good visual outcomes with stable transscleral fixation of the IOL.     

Four-point fixation of posterior chamber intraocular lenses in children with unilateral aphakia

PURPOSE: To evaluate the results of 4-point scleral fixation of posterior chamber intraocular lenses (PC IOLs) in children. SETTING: Mansoura Ophthalmic Center, Mansoura University, Mansoura, Egypt. METHODS: This retrospective study comprised 20 aphakic eyes of 20 children. Preoperative investigations proved the absence of adequate posterior capsule support. All patients had ab externo 4-point scleral fixation of a PC IOL. All preoperative and postoperative data were studied and analyzed. RESULTS: The mean preoperative age was 7.7 years (range 4 to 11 years). The mean follow-up was 19.35 months (range 13 to 30 months). The preoperative findings included a best corrected visual acuity of 6/18 or better in 8 eyes (40%), corneal scarring in 18 eyes, sector iridectomy in 7 eyes, and after-cataract in 4 eyes. The intraoperative complications included vitreous hemorrhage in 2 eyes and slippage of 1 suture in 1 eye. Postoperative complications included mild anterior uveitis in 12 eyes and severe fibrinoid reaction in the anterior chamber in 8 eyes. There were no cases of suture exposure, IOL malpositioning, or infection. Twelve patients (60%) had a visual acuity of 6/18 or better. The cause of the poor visual outcome in many patients was preexisting amblyopia. CONCLUSIONS: The results suggest that 4-point scleral fixation is an option to correct aphakia in children. However, long-term follow-up is important to assess the procedure's safety.
