Outcome of transscleral sulcus fixation of intraocular lens

Purpose: To report the outcome of transscleral sulcus fixation of intraocular lens (IOL). Cases: This review was made on 3,055 eyes that received cataract surgery during the past 52 months. Luxation of the lens developed in 35 eyes (1.1%). Sulcus fixation of IOL was made on 19 eyes of 17 cases. The underlying cases included pseudoexfoliation syndrome 7 eyes, iatrogenic factors 5 eyes, trauma 3 eyes, atopic dermatitis 2 eyes and Marfan syndrome 2 eyes. Results: All the eyes showed good visual acuity after an average of 26 months. Surgically induced astigmatism averaged 1.38 diopters in 7 eyes after sclerocorneal incision of 7 to 12 mm and 0.65 diopters after 3 to 4 mm. The difference was significant (p=0.047). Corneal endothelial cells decreased by an average of 11.8%. The decrease averaged 17.7% in the initial 10 eyes and 5.2% in the latter 9 eyes. The difference was significant (p= 0.029). Iris capture occurred in 4 out of initial 13 eyes (31%). The latter 6 eyes received prophylactic peripheral iridectomy. Iris capture recurred in one of the 6 eyes. Conclusion: Sclerocorneal incision resulted in decreased surgically induced astigmatism in sulcus fixation of IOL. Peripheral iridectomy was effective in preventing iris capture.
