Predicting the necessity of LASIK enhancement after cataract surgery in patients with multifocal IOL implantation
PURPOSE To investigate if the parameters measured routinely prior to cataract surgery with multifocal intraocular lens (IOL) implantation can predict the necessity of additional laser in situ keratomileusis (LASIK) to improve visual outcome. METHODS Records of patients undergoing cataract surgery between January 2008 and December 2009 were reviewed. Individuals satisfied with visual outcome o...
متن کاملPre- and postoperative refraction after cataract extraction with implantation of standard power IOL.
The pre- and postoperative refraction results are reported in 99 patients receiving an anterior chamber lens of standard 19.0 D power after intracapsular cataract extraction. The mean refraction after the operation was -0.76 D, SD 2.13. Apart from eight patients with suspected lenticular myopia, 5% of the patients ended up with a refraction that differed more than +/- 5D from the preoperative v...
متن کاملResolving refractive error after cataract surgery: IOL exchange, piggyback lens, or LASIK.
PURPOSE To evaluate the efficacy, predictability, and safety of three different procedures (intraocular lens [IOL] exchange, piggyback lens implantation, and LASIK) to correct residual refractive error following cataract surgery. METHODS A retrospective multicenter study comprised 65 eyes of 54 patients that underwent phacoemulsification, resulting in a unacceptable final refractive error. Ey...
متن کاملAutorefraction as an outcome measure of laser in situ keratomileusis.
PURPOSE To determine the limits of agreement between subjective refraction and autorefraction before and after laser in situ keratomileusis (LASIK) to assess whether autorefraction is a valid refractive outcome measure of refractive surgery. SETTING Ultralase, Leeds, United Kingdom. METHOD The prospective study involved consecutive preoperative normal patients and post-LASIK patients who ha...
متن کاملLimitations of Intraoperative Aphakic Refraction Technique for Intraocular Lens Power Calculation
Intraocular lens (IOL) power calculations are known to be difficult in eyes that have had corneal refractive surgery and several methods have been proposed to estimate IOL power. Among the methods not requiring preoperative data, the apahakic refraction technique has been successfully used to calculate IOL power in post-refractive cases and other conditions that cause unreliability in standard ...
