Clinical Trial Summary

The study aims at determining the best biometry calculation formula to be used in IOL calculation of cataract patients how previously underwent laser refractive correction surgery

Description:

Patients undergoing laser refractive surgery will will be investigated in means of Pentacam testing and IOL master biometry both preoperative and 6 weeks postoperative to determine which IOL calculation formula is the nearest and most accurate to preoperative records in different refractive sittings.
