When it comes to modern vision correction, choosing the right procedure is one of the most important decisions you’ll make. At Laser Eye Center of Silicon Valley, we guide you through every step, helping you select the best solution for your unique eyes and lifestyle. Two of the most advanced options available today are LASIK and EVO ICL.
This article explores the differences between these procedures, the types of patients they benefit most, and real stories of life-changing results—all to help you make an informed choice.
What Are LASIK and EVO ICL?
LASIK (Laser-Assisted In Situ Keratomileusis) is a laser vision correction procedure that reshapes the cornea, the clear front layer of your eye. By altering the cornea’s curvature, LASIK improves how light focuses on the retina, giving you clearer vision.
EVO ICL (Implantable Collamer Lens) is an additive procedure. Instead of altering your cornea, EVO ICL involves placing a biocompatible lens inside your eye, between the iris and your natural lens. This lens works like a permanent contact lens, correcting your vision without changing your cornea.
Dr. Sudhinder Koushik, a refractive surgeon at Laser Eye Center, explains, “LASIK reshapes the cornea for improved vision, while EVO ICL adds an implantable lens to enhance sight. Both offer excellent results but suit different needs.”

Who Is a Good Candidate?
Candidates for LASIK
- Individuals with mild-to-moderate nearsightedness, farsightedness, or astigmatism.
- Patients with thick, healthy corneas.
Candidates for EVO ICL
- Patients with high prescriptions (e.g., greater than -7.00).
- Individuals with thin corneas or conditions that make LASIK unsuitable.
Dr. Koushik adds, “For patients with thin corneas or extremely high prescriptions, EVO ICL is often the best choice. It’s exciting to offer a solution for patients who thought they were out of options.”
Recovery and Results
LASIK Recovery:
Most LASIK patients experience immediate improvements in vision and return to normal activities within 24–48 hours.
EVO ICL Recovery:
EVO ICL patients often notice significant improvements the day after surgery, with vision continuing to refine over time.
Success Stories from Laser Eye Center Patients
Dr. Koushik shares two powerful examples:
- Military Service Candidate
“A 25-year-old in the military was rejected for LASIK due to thin corneas. EVO ICL was the perfect solution. By adding a lens without altering his cornea, we achieved 20/20 vision the very next day.” - High Prescription Transformation
“A 35-year-old patient with a prescription of -18 struggled daily. After EVO ICL, she experienced phenomenal clarity. She told us it felt like waking up to a new world.”
