Refractive vision correction is a category of surgical procedures that reshape or bypass the eye’s optical imperfections to reduce or eliminate dependence on glasses and contact lenses. These procedures correct refractive errors, which occur when the eye’s shape prevents light from focusing properly on the retina. This guide covers the refractive errors these procedures treat, […]

What is PRK and How Does Photorefractive Keratectomy Correct Vision?

Gary Wortz MD — Wed, 07 Jan 2026 01:57:03 +0000

Photorefractive keratectomy (PRK) is a refractive surgery that removes the corneal epithelium and uses an excimer laser to reshape the underlying stromal tissue, correcting how the eye focuses light onto the retina. PRK treats myopia, hyperopia, and astigmatism without creating a corneal flap. This guide covers how PRK works at the corneal level, who may […]

SMILE

Gary Wortz MD — Wed, 07 Jan 2026 02:00:33 +0000

A Minimally Invasive Laser Vision Correction Procedure SMILE (Small Incision Lenticule Extraction) is a newer refractive surgery technique designed to correct vision with less disruption to the cornea than traditional LASIK. It uses advanced femtosecond laser technology to reshape the eye through a very small incision, without creating a corneal flap. This page explains what […]

A Lens-Based Alternative to Laser Vision Correction

Gary Wortz MD — Thu, 09 Apr 2026 22:23:32 +0000

A Lens-Based Alternative to Laser Vision Correction EVO ICL (Implantable Collamer Lens) is a refractive procedure that corrects vision by placing a biocompatible lens inside the eye rather than reshaping the cornea with a laser. It is designed for patients who may not be candidates for LASIK, PRK or SMILE, or who prefer a non-laser […]

Why It’s Important to Share Your Refractive History with Your Surgeon

Gary Wortz MD — Wed, 14 Jan 2026 23:46:34 +0000

The surgeon needs to tailor calculations and possibly use different techniques to pick the correct lens power for your eye. For instance, if you don’t mention your LASIK and it’s not obvious (LASIK scars can be subtle), the surgical plan might be based on normal-eye formulas, leading to a focus error. Additionally, knowledge of your […]

What Is the Light Adjustable Lens for Post-Refractive Eyes?

Gary Wortz MD — Wed, 14 Jan 2026 23:46:02 +0000

The Light Adjustable Lens (LAL) is a photoreactive silicone intraocular lens that can be customized after cataract surgery through targeted UV light exposure, making it particularly valuable for eyes with prior LASIK, PRK, or radial keratotomy where standard IOL power calculations carry elevated risk of refractive error. This guide covers how the LAL adjustment mechanism […]
