Abstract

Objective Evaluating the influence of risk factor of intraoperative complications such as rupture posterior capsule with vitrous loss on the postoperativemacular thickness using optical coherence tomography (OCT). Background Cystoid macular edema (CME) remains an important cause limiting favorable visual outcomes following cataract surgery. Thecomplicated cataract surgery (with posterior capsular tear) could be a strong risk factor for development of macular edema than the uneventful surgeries. Methods 70 cases, 62 patients underwent phacoemulsification surgeries divided into 5 groups anda healthy control group Group I: Uncomplicated cataract surgery (non-diabetic) Group II: Uncomplicated cataract surgery (Diabetic patient) Group III: Complicated cases with PCR and Ant vitrectomy (non-diabetic) Group IV: Complicated cases with PCR antvitrectomy (Diabetic patient) Group V: Complicated cases with PCR ant vetrectomy, AC IOL Group VI: Normal cases without cataract extraction Patients follow up by Visual acuity, fundus ,IOP and Maculathickness map using OCT scan (RS-3000RetinaScan, NIDEK Co., Japan) was conducted after 1 month. Results We found that, macular thickness was significantly higher after cataract surgeries with posterior capsular tear than the unevetiful surgeries, Also diabetes did not influence significantly the thickening of the macular regions after uncomplicated cataract surgery. Conclusion After cataractsurgery, there is non significant increase of foveal thicknessThe complicated cataract surgeries with rupture posterior capsule and vitrous loss may be a risk factor, while diabetes may not be a risk factor for development of post operative macular oedma.
