ABSTRACT
Objective: To evaluate the efficacy and complications of 20 gauge vitrectomy via corneal approach for the management of congenital cataract
Method: We performed anterior capsular vitreorhexis, lens matter aspiration [LMA], primary posterior vitrectorhexis and anterior vitrectomy via corneal approach using 20 gauge vitrectomy system in children younger than two years of age with congenital cataract between January 2014 to December 2014. The intra and postoperative complications were observed
Results: Twenty nine eyes of 21 children were included in this study. Congenital cataract surgery using 20 gauge vitrectomy system via corneal approach did not reveal any intra operative complication. Post operatively all children were able to freely open their operated eyes. Conjunctival congestion at the incision site in four eyes and mild anterior chamber reaction in 8 eyes were seen on 1[st] day which resolved at one week follow up. Other major post operative complications such as inflammatory membrane, irregular pupil, posterior/anterior syneache and opacification of visual axis were not seen during follow up period
Conclusion: The 20-gauge vitrectomy system via corneal approach is easy to perform, is less time consuming, safe and effective for the management of congenital cataract in younger children
ABSTRACT
To assess the visual outcome and complications in patients after Ab-externo scleral fixation of intraocular lens in pediatric age group [15 years or less]. This quasi experimental study was conducted at Isra Postgraduate Institute of Ophthalmology, Al-Ibrahim Eye Hospital, Karachi, from January 2012 to December 2012. All cases included were worked up according to the protocol. All patients underwent Ab-externo scleral fixation of IOL under general anesthesia. Patients were followed up at 1stday, 1[st] week, 1[st] month, 2[nd] month and 3[rd] month. Complete eye examination including best-corrected visual acuity and complications were noted on each visit. Thirty patients were included in the study, with mean age of 8.6 years [ +/- 3.93569]. Most of the patients, 20 [66.7%], had visual acuities of 6/18 or better. No complication was seen in 18 [60%] of the patients intra operatively while soft eye was observed in 7 [23.3%] of the patients. Another complication noted was vitreous hemorrhage, which was seen in 5 [16.7%] patients. Most common post-operative complication was Uveitis followed by astigmatism. Lens dislocation and iris abnormalities were seen in only one patient. Most of the patients showed significant visual improvement after surgery. Ab-externo scleral fixation of an IOL was found to be safe and showed favorable postoperative results with fewer complications
