Brief 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

Condition or disease
Cataract Refractive Errors

Detailed 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.
