Intraocular contact lens (ICL’s) are an excellent option for patients who are not suitable to have corneal refractive surgery (LASIK, PRK, SMILE).
ICL surgery gives patients excellent visual results. The patient’s natural lens remains in place which means you maintain your normal ability to accommodate (see distance and close up). The procedure is reversible and the lenses can be removed if not tolerated.
Surgery is done in a Hospital Theatre. A laser iridotomy may be needed before surgery in some cases. The eye is anesthetized using a topical anesthetic drop or peri-ocular injection. Each eye is operated on separately.
This is usually done on separate days but can be done in the same admission. The ICL device is placed between the normal lens and iris. The eye is washed out and an antibiotic injected into the eye. Patients are seen immediately after surgery to ensure the lens is sitting perfectly.
These lenses are excellent for patients who are not suitable to have LASIK/PRK. Patients who have high myopia (>-10D), high astigmatism or hyperopia with deep anterior chambers are best suited to have this surgery.
Patients whose cornea is too thin to have LASIK, PRK or SMILE® may be good candidates to have ICL surgery.
Mr. X is a 28-year-old tradesman. He is a keen surfer. He has had poor vision since he can remember. His refraction is +5.00/-1.25 in his right eye and +5.50/-1.00 in his left eye. He can’t tolerate contact lenses and really struggles to see when working and surfing.
He is not a candidate to have LASIK/PRK/SMILE as he has deep anterior chambers.
He underwent ICL surgery (both eyes on the same day). He had to have laser iridotomies 1 month before surgery.
Now he sees perfectly for all distances and can work and surf without any visual problems. He gets seen on a yearly basis to make sure he doesn’t develop cataract or glaucoma.
