High myopia above -10 dioptres presents a specific challenge for refractive surgery. LASIK works by reshaping the cornea with an excimer laser, but it removes corneal tissue to do so. At high powers the amount of tissue required to achieve the correction exceeds what the cornea can safely spare. An ICL is placed inside the eye between the iris and the natural crystalline lens, correcting the refractive error without touching the cornea at all.

According to Dr. Mayank Bansal, a leading refractive surgeon at the Best Eye Hospital in Delhi,
“For anyone above -8 to -10 dioptres, ICL is not simply an alternative to LASIK it is the safer, more optically superior procedure. The cornea is left entirely untouched, and the correction is reversible if the patient’s prescription changes significantly over time.”

How Does ICL Compare to LASIK for High Myopia?

The two procedures address the same goal through fundamentally different mechanisms. That difference determines which is appropriate for any given patient and prescription.

The cost difference narrows considerably when accounting for optical outcome quality at high powers. A -12D patient achieving 6/6 uncorrected vision with excellent contrast sensitivity through an ICL gets a materially better visual result than the same patient managed at the edge of safe LASIK territory.

Who Is the Ideal Candidate for ICL at High Myopia?

ICL candidacy is determined by anterior chamber depth, endothelial cell count, and the vault the lens will create between itself and the natural crystalline lens after implantation.

• Prescription range: The Staar EVO Plus ICL platform covers myopia from -0.5 to -20.0 dioptres with cylinder correction up to -6.0 D via the toric variant.
• Anterior chamber depth: A minimum anterior chamber depth of 2.8 mm is required to accommodate the ICL safely. 
• Endothelial cell count: ICL implantation requires adequate corneal endothelial cell density, typically above 2,000 cells per mm squared. 
• Age: ICL surgery is performed between ages 21 and 45 in most protocols. Below 21, refraction may still be changing. 
• Retinal health in high myopes: High myopia carries an intrinsically elevated risk of retinal pathology including lattice degeneration, peripheral breaks, and retinal detachment. 
• Post-ICL monitoring: Annual review of vault height, endothelial cell count, and IOP is standard practice for all ICL patients. 

The ideal ICL candidate is a high myope with adequate anterior chamber depth, a healthy endothelium, and a prescription stable for at least 12 months who wants spectacle-free vision without the irreversible corneal tissue removal that LASIK requires.
