INCIDENCE OF CME AFTER HYDROPHILIC AND ACRYLIC IOL IMPLANTATION - OCT RESULTS

The aim of this study was to estimate frequency of cystoid macular edema in cases of cataract surgery (phacoemulsification) without complications after implantation of two different types artificial lenses-acrylic hydrophilic and acrylic hydrophobic. Prospective study involved 48 eyes of 36 patients aged 60-70 (women-65%, men-35%). Before initating study objects (eyes) were equally divided into two groups (I and II), n-24 in each). A criterion for division into groups was a type of implanted artificial lens-hydrophilic and hydrophobic. Cystoid macular edema (CME) was not detected among neither group of patients. In both groups (with hydrophilic and hydrophobic intraocular lens), average central retinal thickness (CRT) before surgery was 250±0.005 micron. After surgery, on 5th-7th days average increase of CRT was 30±0.080 micron (p<0.05) according to assessment on optical coherence tomography MM6 scan. Among patients with hydrophilic and hydrophobic lens (in I and II groups) CRT increase tendency was not significantly different statistically. Initial and post-operative data was not different neither of group according to gender (p<0.5). Research findings show that the cystoid macular edema does not develop upon operative treatment of cataract in post operative period of implantation of hydrophilic as well as hydrophobic intraocular lens. Quality of change of central retinal thickness does not have clinically valuable expression, it cannot have impact on patient`s visual acuity and accordingly, parameter of its life quality. Therefore, the main cause of CME is operative method of cataract as well as somatic state of the patient and accompanying diseases. Intra-operative complications - damage of iris and ciliary body, excessive prostaglandin synthesis and production of free radicals etc. Analysis of the study results have revealed that during cataract surgery cystoid macular edema have not developed in the post-operational period after implantation of hydrophilic as well as hydrophobic artificial lens. Degree of change in CRT is not clinically important.
