## What is Eyedea Refractive?

Clinical calculator for Refractive Surgery, designed to support pre- and post-operative evaluation of LASIK, Lenticular Extraction (SMILE), and PRK, based on current medical literature.

From the patient's pre-operative data, it calculates post-nomogram refraction, central and maximum ablation, residual stromal bed, PTA/PSTA, LASIK Ectasia Risk Score, predicted final keratometry, mitomycin time, and more.

In postoperative evaluation, it analyzes spherical refractive outcome along with PTA and keratometry variation, classifying results into objective clinical categories.

Results are intended as clinical decision support and should always be correlated with the patient's in-person evaluation.
