Abstract:
We studied the postoperative results of 38 patients (40 eyes) who received the implantation of IOGEL 1103 (Alcon, U.S.A.), a single piece intracapsular fixing hydrogel lens. Scleral pocket incision was done tangentially 2mm posterior to the surgical limbus and 4mm in length. The diameter of continuous curvilinear capsulorhexis (GCC) was about 5mm and intercapsular phacoemulsification was carried out. No suture or single 10-0 nylon suture was used for the closure. Uncorrected visual acuity of 20/40 or better was observed in 70% of all cases at 1 week postoperatively and in 90% at 2 months postoperatively Mean keratometric astigmatism analized by vector analysis was 0.65 diopter (D) at 1 week postoperatively and -0.13D at 8 weeks postoperatively and the changes from preoperative astigmatism was 0.31D at 1 week postoperatively, and 0.43D at 8 weeks postoperatively. Intraocular lens (IOL) was damaged during insertion into the capsular bag in 7.5%. Fibrinoid membrane on IOL surface formed in 5% and cystoid macular edema was shown in 2.5%. Severe shrinkage of anterior capsule (less than 3 mm in diameter) was shown in 22.5% at 8 weeks postoperatively. Early postoperative results revealed that IOGEL 1103 is relatively stable in the capsular bag and induces good visual recovery with less astigmatism. However, a method to prevent the postoperative shrinkage of anterior capsule and a proper shape of hydrogel lens should be investigated in the future.
