Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
