Comparison of Corneal Topography in Eyes Before and One Month After the Phacoemulsification Procedure

Abstract

Antares Placido topographer CSO had been used to measure 50 eyes corneas at Ophthalmological Clinic of the Greek Red Cross hospital «Korgialeneio -Benakeio in collaboration with University of West Attica and their refractive maps were taken. The refractive power map was taken before cataract surgery with the method of phacoemulsification. The keratometric measurements for 3 & 5mm were recorded before and one month after surgery. The correlation of the K 1 , K 2 readings before and one month after the phacoemulsification procedure, do not cause changes in the refractive power of the two main meridians of the cornea of patients, in order to alter the final astigmatism refractive post-operative effect, to a statistically significant degree.

A comparative study of corneal topographical and central corneal thickness changes in diabetics and non-diabetics before and after phacoemulsification: A study protocol

“…The sample size was calaculated using sample size formula with designed error of margin (15) Preoperatively and one month after phacoemulsification surgery, topography was conducted on patients, corneal refractive forces were statistically analyzed, surgically produced astigmatism was researched, and comparisons between before and after the procedure were made.…”
