An implantable collamer lens adds optical power without removing the natural lens
The foldable lens is inserted through a small incision and positioned behind the iris. It may suit selected adults with myopia who are not ideal corneal-laser candidates.
The operation is intraocular and carries different risks from laser correction. Anterior-chamber depth, endothelial health, pupil, angle, prescription stability and retinal condition matter.
Although the lens can be removed, cataract, pressure problems, endothelial loss or retinal events may not be fully reversible.
Who may be considered?
Specialist review may help when the diagnosis, symptoms and previous treatment create a focused question about implantable collamer lens surgery.
- An adult within the approved refractive and age range for the chosen lens.
- Stable myopia with or without treatable astigmatism.
- Adequate anterior-chamber depth and endothelial-cell reserve.
- No uncontrolled glaucoma, cataract, active inflammation or unstable retinal disease.
What the specialist team must confirm
Review cycloplegic refraction, anterior-chamber depth, angle, white-to-white or other sizing measures, endothelial cells, corneal tomography, pupil size, lens clarity, pressure and dilated retina.
Key points for this treatment
From refractive screening to long-term implant surveillance
Both eyes are assessed individually and postoperative reviews look beyond visual acuity to implant position and ocular health.
Early pressure and long-term lens checks matter
Vision may improve quickly, but early pressure, inflammation and lens position require review. Prescribed drops and activity precautions support healing.
Long-term checks monitor cataract, endothelial cells, angle, pressure, vault, refraction and retina. Glasses may still be needed for some tasks.
Risks, limits and realistic expectations
Risks include infection, inflammation, pressure rise, glare or halos, residual prescription, lens rotation, cataract, endothelial-cell loss, retinal detachment and additional surgery.
Severe pain, headache with nausea, rapidly reduced vision, marked redness, flashes or a curtain shadow after implantation requires urgent ophthalmic review.
