PURPOSE: To evaluate anatomical and functional results of cataract extraction and IOL implantation, together with posterior capsulectomy and anterior vitrectomy in children. MATERIALS AND METHODS: Cataract extraction and IOL implantation with posterior capsulectomy and anterior vitrectomy was performed in 32 eyes of children between 17 months and 8 years old. Patients were followed up for a mean period 36 months (from 6 months to 5.5 years). RESULTS: Good anatomical results were achieved in all, except 2 cases. One eye required removal of opacifications located posterior to the IOL In the second eye membrane from the anterior surface of the lens were excised. Final postoperative visual acuity in eyes with bilateral cataract was 0.59, whereas in unilateral cataract 0.25. Half of the children with bilateral cataract has significantly worse BCVA in one eye. CONCLUSIONS: Cataract extraction and IOL implantation with posterior capsulectomy and anterior vitrectomy in young children gives good anatomical results. Functional results are better in bilateral congenital cataract, comparing to unilateral cases. To achieve good functional results, visual rehabilitation is necessary.  相似文献

Background

Long-term outcomes of intraocular lens (IOL) implantation for congenital cataract in children under 2 years old are still undetermined.

Methods

We retrospectively reviewed all cases of bilateral congenital cataract who had undergone simultaneous bilateral cataract removal with posterior capsulotomy and central anterior vitrectomy between 1990 and 2010. Patients randomly underwent primary IOL implantation or secondary IOL implantation after a period of contact lens wear. The two groups were compared for visual outcome and complications during follow-up.

Results

Cataract removal and primary IOL implantation was performed in 30 eyes (15 patients; nine males, six females) at a mean age of 6.8?±?4.2 months. After 79.31?±?63.4 months, best-corrected visual acuity (BCVA) was 0.53?±?0.36 EDTRS LogMAR. In 36 eyes (18 patients, 11 males, seven females) the lens was removed at a mean age of 5.42?±?2.80 months, and after 32.0?±?6.1 months of contact lens utilization, secondary IOL implantation was performed. After 109.0?±?33.8 months, BCVA was 0.54?±?0.4 ETDRS LogMAR. The association between age at surgery and final visual acuity and the difference between the two groups concerning type of cataract at baseline, BCVA and refractive error at last visit, incidence of posterior capsular opacification, glaucoma, strabismus, and nystagmus during follow-up were not significant (p?>?0.05). Myopic shift was more frequent in eyes undergone primary IOL implantation (p?<?0.001).

Conclusions

Similar visual outcome and complications were observed during long-term follow-up after both primary and secondary IOL implantation following simultaneous bilateral congenital cataract removal with posterior capsulotomy and central anterior vitrectomy.  相似文献

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.  相似文献

PURPOSE: To evaluate the results of bilateral simultaneous cataract surgery in adult and pediatric patients under local or general anesthesia. SETTING: Department of Ophthalmology, In?nü University, Turgut Ozal Medical Center, Malatya,Turkey. METHODS: Eighty-two eyes of 41 patients were included in the study. Twelve of 17 pediatric patients with congenital cataract had bilateral simultaneous lensectomy, posterior capsulotomy, and anterior vitrectomy; 5 patients, aged 10 to 19 years, had bilateral extracapsular cataract extraction (ECCE) with posterior chamber intraocular lens (PC IOL) implantation. Forty-eight eyes of 24 adult patients had bilateral simultaneous ECCE with primary (43 eyes) or secondary (5 eyes) PC IOL implantation. Local anesthesia was administered to 20 adult patients by retrobulbar injection; the other cases were performed using general anesthesia. The procedures were treated as 2 separate surgeries in the same session; care was taken to ensure surgical asepsis. RESULTS: No serious intraoperative complications occurred such as posterior capsule rupture, vitreous loss, endophthalmitis, and anesthesia-related problems. Of patients tested, 84.4% achieved a final best corrected visual acuity of 6/12 or better and 31.0%, of 6/6 or better. CONCLUSIONS: Simultaneous bilateral cataract surgery was not associated with an increased rate of complications, and visual results were good. If strict rules of surgical asepsis are followed, this may be a useful option in a variety of bilateral cases using general or local anesthesia.  相似文献

PURPOSE: The optimal role of intraocular lenses (IOLs) in infants remains a controversial topic. Some ophthalmologists advocate correction with a contact lens (CL), whereas others recommend an IOL correction. Our study compared visual acuity, ocular alignment, retreatment rate and binocular vision outcomes in children treated with these two methods at our clinic. METHODS: This study included 41 children with unilateral congenital cataract who underwent cataract surgery with posterior capsulorhexis and anterior vitrectomy, coupled with (IOL group, n=18) or without (CL group, n=23) primary IOL implantation. All infants underwent the first surgery during the first 12 months of their life and they were operated on in the period from 1994 to 1999. The mean age at surgery was 3.11+/-2.65 months (range: 28 days to 11 months). All patients were prescribed the same half-time reduced occlusion therapy. Good cooperation of the parents and good compliance with patching were the necessary conditions to include a patient in the study. Between January and February 2003, the final visual acuity and binocular vision outcomes were examined. RESULTS: The mean final visual acuity (logarithm of the minimum angle of resolution) of the operated eye was 0.43+/-0.33 for the IOL group and 0.58+/-0.39 for the CL group (p=0.14). The mean interocular difference in visual acuity was 0.22+/-0.29 for the IOL group and 0.56+/-0.31 for the CL group (p=0.042). The reoperation rate was 78% in the IOL group compared with 35% in the CL group (p=0.017). Esotropia or exotropia of more than 8 prism diopters were present in 55% of children (10/18) in the IOL group compared with 83% of children (19/23) in the CL group (p=0.039). CONCLUSIONS: We suggest that correction of aphakia after unilateral congenital cataract surgery with primary IOL implantation results in improved visual acuity, improved binocular vision outcome and less occurrence of strabismus, but a higher rate of complications requiring reoperation. Further studies with a larger pediatric patient group are necessary to confirm the optimal treatment of aphakia after unilateral congenital cataract extraction.  相似文献

Intra-ocular lens (IOL) implantation in a growing eye of a young child brings several problems unique to this age group. Better understanding of the rate of refractive growth in children's pseudophakic eyes may help predicting future refractions in these eyes more accurately. Opacification of the posterior capsule, if remained intact, interferes with visual rehabilitation in children. Primary posterior capsulectomy and anterior vitrectomy provides the clarity of visual axis. Optical rehabilitation of children with unilateral aphakia is usually problematic. Posterior chamber IOLs are preferred to anterior-chamber IOLs for secondary implantation. In the absence of adequate capsular support and contact lens intolerance, a scleral-fixated IOL can be implanted. Scleral fixation of a posterior chamber IOL has encouraging short-term results but the long-term risks are not known yet. Intra-ocular lens implantation in infants is associated with major complications and is not recommended at present. The occurrence of open angle glaucoma is a sight-threatening late complication of pediatric cataract surgery. Intra-ocular lens implantation plays a protective role against aphakic glaucoma in children.  相似文献

PURPOSE: The method of correcting aphakia after unilateral cataract extraction during infancy is controversial. Some authorities advocate correction with an intraocular lens (IOL) whereas others advocate correction with a contact lens (CL). We compared grating visual acuity, alignment, and reoperative outcomes in age-matched children treated with these 2 modalities at 5 clinical centers. METHODS: Twenty-five infants born in 1997 or 1998 with a dense unilateral congenital cataract who had cataract surgery coupled with (IOL group, n = 12) or without (CL group, n = 13) primary IOL implantation were enrolled in this study. All patients were prescribed half-time occlusion therapy. In July 1999, their grating visual acuities, ocular alignments, and reoperation rates were assessed. RESULTS: The mean grating visual acuity (LogMAR) for the affected eye was 0.70 +/- 0.32 for the IOL group and 0.87 +/- 0.31 for the CL group (P =.19). The mean interocular difference in grating visual acuity was 0.26 +/- 0.30 for the IOL group and 0.50 +/- 0.28 for the CL group (P =.048). The incidence of strabismus (>10 PD) was 75% in the IOL group compared with 92% in the CL group (P =.24). The incidence of reoperations was 83% in the IOL group compared with 23% in the CL group (P =.003). CONCLUSIONS: Our preliminary data suggest that correcting aphakia after unilateral congenital cataract surgery with primary IOL implantation results in an improved visual outcome but a higher rate of complications requiring reoperation. A randomized clinical trial, the Infant Aphakia Treatment Study, is planned to further study the optimal treatment for aphakia following unilateral cataract extraction during infancy.  相似文献

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.  相似文献

To evaluate the results of congenital cataract extraction and postoperative visual function, we retrospectively reviewed the records of 95 patients who underwent pars plana (plicata) lensectomy or aspiration surgery. Forty-nine percent of the patients with bilateral aphakia and 25% with bilateral pseudophakia had a Landolt visual acuity of 0.5 or above at the final visit. The figures were 31% and 66% for patients with unilateral aphakia and pseudophakia, respectively. Eight patients (16.3%) with bilateral and 2 patients (5.8%) with unilateral cataract for whom contact lenses were prescribed after surgery attained fine stereopsis. Five of 8 patients (62.5%) with unilateral cataract who had intraocular lens implantation ended up with gross or fine stereopsis. We stress that very early surgery and optical correction in the sensitive period of binocular visual development should be instituted, especially in the presence of dense opacities. A good postoperative visual outcome can be achieved in patients undergoing late surgery if the opacities are light or partial in nature. We also reemphasize the importance of aggressive and diligent visual rehabilitation and occlusion therapy against amblyopia.  相似文献

PURPOSE: To describe a technique for suture fixation of silicone intraocular lenses (IOLs) to the iris and compare the outcomes to those in published data. SETTING: Subspecialty cornea/anterior segment private practice, Indianapolis, Indiana, USA. METHODS: This retrospective review comprised 121 consecutive cases of secondary IOL implantation or IOL exchange between 1993 and 1998. All cases had concurrent anterior or posterior vitrectomy. Intraocular lens exchange was performed in 96 eyes, secondary IOL implantation in 20 eyes, and primary IOL implantation in 5 eyes. Penetrating keratoplasty (PKP) was performed concurrently in 93 eyes, extracapsular cataract extraction in 1 eye, intracapsular cataract extraction in 2 eyes, pars plana lensectomy in 2 eyes, and Molteno tube shunt placement for uncontrolled glaucoma in 1 eye. Outcomes measured were graft survival, visual acuity, new onset or worsening of glaucoma, and complications related to surgery. RESULTS: Graft survival at last follow-up was 89.2% in patients having PKP. Visual acuity was 20/80 or better in 58.3% and 20/40 or better in 30.5% of eyes with transplants. Without transplants, visual acuity was 20/80 or better in 82.0% and 20/40 or better in 57.1%. Glaucoma developed or worsened in 24.7% and improved in 16.1% with transplants; it developed or worsened in 7.0% and improved in 17.8% without transplants. Retinal detachment occurred in 1 eye with a transplant. In the nontransplant group, major complications were bullous keratopathy (n = 2) and tilted IOL (n = 1). CONCLUSIONS: Iris fixation of posterior chamber silicone IOLs may decrease the possibility of late suture breakage and dislocation of the IOL, as well as the risk of endophthalmitis. Graft survival, visual acuity, glaucoma, and complications are similar to those of other methods of IOL fixation reported in the literature.  相似文献

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.  相似文献
