The goal of this observational study is to evaluate the long-term refractive outcomes of advanced intraocular lens (IOL) power calculation formulas in cataract patients with posterior corneal elevation (PCE ≥ 15 μm).
The main question it aims to answer is:
Do PK-based formulas provide superior refractive accuracy compared with Without-PK-based formulas in patients with elevated posterior corneal surfaces?
Participants undergoing routine cataract surgery will have their biometry measured by both Pentacam AXL and IOLMaster 700, and postoperative refraction will be collected at 1 month, 3 months, and 6 months postoperatively.
