Cataract surgery in patients with Behçet's disease

PURPOSE: To evaluate the outcomes and complications of cataract surgery in patients with Beh?et's disease. SETTING: Department of Ophthalmology, Hacettepe University School of Medicine, Ankara, Turkey. METHODS: Thirty-three eyes of 26 patients with Beh?et's disease that had extracapsular cataract surgery between January 1993 and July 1999 were analyzed retrospectively. The mean age of the patients was 38.9 years (range 20 to 54 years). The mean postoperative follow-up was 22.9 months (range 6 to 66 months). RESULTS: Extracapsular cataract extraction (ECCE) was performed in 22 eyes with and in 6 eyes without intraocular lens (IOL) implantation. Phacoemulsification with IOL implantation was performed in 5 eyes. Postoperatively, the visual acuity was better in 29 eyes (87.8%) and was 0.5 or better in 14 eyes (42.4%). Posterior segment complications of Beh?et's disease, mainly optic atrophy and macular alterations from preoperative inflammatory episodes, restricted final acuity. No significant difference was detected in postoperative inflammation among the types of surgery; that is, ECCE, ECCE with IOL implantation, and phacoemulsification with IOL implantation. A neodymium:YAG laser posterior capsulotomy was performed in 3 cases. CONCLUSIONS: In patients with Beh?et's disease, inflammation after extracapsular surgery was mild when surgery was performed after at least 3 months of no inflammatory signs. The results show that the outcomes of extracapsular cataract surgery mainly depend on the degree of preoperative posterior segment involvement.     

The results of cataract extraction and intraocular lens implantation in patients with Behçet's disease

PURPOSE: To evaluate the results of extracapsular cataract extraction (ECCE) and intraocular lens (IOL) implantation in patients with Beh?et's disease. METHODS: Retrospective study was based on 19 uveitic eyes of 12 patients with Beh?et's disease who underwent classic ECCE with IOL implantation in 5 eyes and phacoemulsification with IOL implantation in 14 eyes between 1993-1999. RESULTS: In eyes with Beh?et's uveitis 0.5 or better postoperative visual acuity was found in 21% at the end of mean 34.2-4.6 (range 5 to 66) months follow-up. The most frequent postoperative complications were posterior capsule opacification in 9 (47%), posterior synechiae in 5 (26%), anterior synechiae in 3 (16%). Anterior and posterior synechiae in the phacoemulsification group were less than those in the ECCE group (respectively p<0.05 and p<0.01). CONCLUSIONS: In eyes with chronic Beh?et's uveitis, cataract extraction and IOL implantation by phacoemulsification had fewer postoperative complication than ECCE, but most of the patients had low visual acuity due to preoperatively existing optic atrophy and/or inflammatory degeneration or edema of macula.

Bilateral cataract surgery in adult and pediatric patients in a single session

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.     

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.
