Effects of different limbal incision methods during phacoemulsification and intraocular lens implantation on corneal higher order aberrations
摘要
Abstract
Objective To examine the changes in corneal higher order aberration in cataract phacoemulsification and intraocular lens ( IOL) implantation operated with either 2.2 mm or 3.0 mm limbal incision.Methods This is a ret-rospective analysis of 72 cases (130 eyes) of cataract surgeries.Patients received phacoemulsification and IOL implantation with either 2.2 mm limbal incision (36 patients) or 3.0 mm limbal incision (36 patients).Corneal surface aberrations were measured before and up to 3 months after the surgery.Higher order aberrations ( HOA), including total HOA ( tHOA) , coma ( Coma) , and primary spherical aberration ( SA) were analyzed.Results Baseline tHOA, Coma and SA values were not different between two groups of patients.After surgery, SA values improved in patients who received smal-ler incisions (i.e., 2.2 mm) and were higher than those of patients who received larger incisions (3.0 mm;P <0.05). In patients who received larger incisions, tHOA improved significantly but was higher than other patients at 3 months ( P <0.05).Conclusion Corneal surface HOA did not change significantly after surgery with either 2.2 mm or 3.0 mm limbal incision.Minor alterations in higher order aberrations is more likely due to surgical quality.关键词
