RESUMO
To evaluate the success rate of surgical corrections of constant and intermittent exotropias. A case series. Al-Ibrahim Eye Hospital, Karachi, from July 2011 to December 2012. Patients having primary exotropia [deviation 15 - 45 prism diopters [PD]] were included. Patients with either constant exotropia or basic intermittent exotropia underwent unilateral surgery of lateral rectus recession [maximum up to 10 mm] and medial rectus resection [up to 6 mm]. Similarly, when patients had intermittent distance exotropia, underwent bilateral lateral rectus recession [maximum up to 10 mm]. Final outcome was considered at the end of 2 months at which achievement of = 10 PD of exotropia was considered as a success. Out of 248 patients, 170 [68.5%] had either constant exotropia or basic intermittent exotropia, while 78 [31.5%] had intermittent distance exotropia. Mean angle of deviation before surgery was 49.23 prism diopters while after surgery, mean angle of deviation was 8.54 prism diopters. Overall success rate was 81.45% [n=202]. In case of unilateral lateral rectus recession and medial rectus resection surgery, the success rate was 85.14% while success rate in case of bilateral lateral rectus recession was 65.21% [p=0.001]. Unilateral lateral rectus recession and medial rectus resection for surgical correction of exotropia had better surgical success rate as compared to bilateral lateral rectus recession.

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
