EFFECT OF VARIABLE PHACO TIMES OF CONSTANT PHACO ‎POWER ON MACULAR THICKNESS

Abstract

Background: Various factors involved in phaco can influence the tissue structures of the eyeball Ultrasonic energy should be taken into consideration as a risk factor that may affect the structure of the tissue in the eyeball. Objective: To evaluate changes on macular thickness before and after phacoemulsification surgery with variable Phaco Times and constant phaco ‎power by Optical Coherence Tomography (OCT). Patients and methods: A prospective observational clinical study on 40 eyes with Nuclear cataract grade II-III. All patients under went full medical and ophthalmic history, history of ocular surgeries, complete ophthalmic examination include ingvisual acuity: Uncorrected VA (UCVA) and best corrected VA (BCVA),Anterior segment examination using Slit-lamp bio microscopy, Intraocular pressure (IOP) measurement by applanation tonometry, Fundus examination, OCT was done preoperatively and then 4-6 weeks postoperatively. Results: In patients with Nuclear cataract, there was no significant correlation between postoperative 4-6 weeks macular thickness (MT) with phaco time. Conclusion: After phacoemulsification surgery with variable phaco times and constant phaco power, there was no significant correlation between postoperative 4-6 weeks macular thickness (MT) with phaco time.
