Abstract：Objective: To evaluate and compare the efficacy between clear corneal small incision and Superior Scleral Tunnel Incision in patients undergoing secondary intraocular lens implantation with suture fixation. Methods: Retrospectively analyzed, 40 aphakic patients performed clear corneal small incision treatment (Group A; 40 eyes) and 41 aphakic patients who underwent traditional corneoscleral incision surgery (Group B; 41 eyes) in Lishui Central Hosptial from 2009 January to 2015 June. Analyzed postoperative complications including visual acuity, surgically-induced astigmatism, hyphema, corneal edema and intraocular lens deflection at 1 day, 1 week, 1 month and 3 months, after surgery. Results: Camparted A and B groups, the difference of visual acuity and surgically-induced astigmatism, in different time after surgery was statistically significant (P<0.05 ), The incidence rate of hyphema, corneal edema and intraocular lens deflection from Group-A was less than Group B, and the difference of incidence rate of corneal edema was statistically significant (P<0.05). Conclusion: The secondary intraocular lens suture through tunnel incision on the temporal clear cornea plays a positive role to enhance the postoperative uncorrected visual acuity and decrease complications for patients of aphakia, which is important supplement of posterior chamber intraocular lens.
