What is Implantable Collamer Lens (ICL) surgery?
Implantable Collamer Lens (ICL) surgery is a vision correction procedure designed to treat refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Unlike
LASIK
or PRK, ICL surgery involves implanting a thin, collamer lens inside the eye to correct the refractive error and improve visual acuity. This procedure is an alternative for individuals who might not be suitable candidates for corneal refractive surgeries.
Indications of Icl Surgery Procedure
ICL (Implantable Collamer Lens) surgery is typically indicated for individuals who have certain refractive errors and meet specific criteria. The procedure can be particularly beneficial for those who:
-
Have High Degrees of Myopia (Nearsightedness): ICL surgery can effectively correct severe myopia that might not be suitable for other vision correction methods like LASIK or PRK.
-
Have Moderate to High Degrees of Hyperopia (Farsightedness): ICL surgery can be an option for individuals with significant hyperopia, especially if they are not suitable candidates for other refractive surgeries.
-
Have Astigmatism: ICLs are available in toric designs, which can correct astigmatism along with nearsightedness or farsightedness.
-
Are Seeking a Reversible Option: Unlike some other refractive surgeries, ICL surgery does not involve altering the cornea's tissue. This means the procedure can be reversed by removing the ICL if necessary.
-
Have Thin Corneas: Individuals with thin corneas might not be suitable candidates for LASIK or PRK. ICL surgery can be a viable option as it doesn't involve corneal tissue removal.
-
Have Dry Eyes or Ocular Surface Issues: Some individuals who experience dry eyes or other ocular surface issues might not be suitable candidates for laser-based refractive surgeries. ICL surgery can be considered in such cases.
-
Are Looking for High-Quality Vision Correction: ICL surgery can provide excellent visual outcomes with minimal risk of inducing higher-order aberrations, leading to better quality of vision, reduced glare, and halos, especially in low-light conditions.
-
Are Not Candidates for LASIK or PRK: Some individuals might not meet the criteria for LASIK or PRK due to various reasons, such as corneal irregularities or previous eye surgeries. ICL surgery can be a suitable alternative.

-
Lens Positioning:
- The ICL unfolds and positions itself correctly within the eye.
- The doctor will ensure the lens is properly aligned and centered.
-
Postoperative Process:
- The small incision is self-sealing and typically does not require stitches.
- No need for a patch, and you can often see relatively well immediately after the surgery.
-
Recovery Room:You'll be moved to a recovery area where you'll be monitored for a short time as the effects of any sedation wear off.
-
Discharge:After a short period of observation, you'll be allowed to go home, accompanied by a friend or family member.
-
Follow-Up Appointments:You'll have follow-up appointments to assess your healing and visual acuity in the days, weeks, and months following the surgery.
-
Eye Drops and Medications:
- Your doctor will prescribe eye drops to prevent infection and inflammation and to promote healing.
- You'll also receive instructions on using artificial tears to keep your eyes moist.
-
Restrictions and Care:You'll be advised to avoid rubbing your eyes and engaging in activities that could potentially cause trauma to the eyes during the initial healing phase.
-
Visual Improvement:Many patients experience improved vision within a day or two after the surgery.
Who will Treat for Icl Surgery Procedure
