The ICL is implanted between the iris and the normal lens, which will keep it away from the cornea and closer to the normal lens’ natural position. This positioning makes these lenses safer than the old iris clip lenses, as in theory they don’t rub against the back of the cornea which typically damages it and causes vision deterioration.
The procedure is usually done under local anaesthesia. It involves making a microscopic corneal incision through which the ICL lens would be implanted behind the iris. The incision is usually watertight and doesn’t need suturing.
In general, the procedure is painless and the pain is controlled with topical anaesthetic. One of the possible risks involved with the surgery could be bleeding inside the eye, which is usually self-resolving. Increased eye pressure might be associated with ICL surgery and if it becomes a long-term issue, ICL explantation (removal) might be considered. The risk of cataract formation (normal lens cloudiness) over the 10 years after surgery is less than 1%. However, if the cataract was visually significant, another surgery might be needed to remove it and improve vision.
After surgery the patient should avoid rubbing the eye. Although the lens sits securely behind the iris, there is a theoretical risk of causing damage to the cornea if the patient forces the cornea against the artificial lens through rubbing the eye. Even in case of no lens implant in the eye, excessive eye rubbing could cause damage to the cornea and increased lid laxity among other ocular detrimental effects, so it should be avoided.
The materials used to make the ICL lens are inert, meaning they can stay inside the eye without causing any reactive activity. If cataract developed over the years, it might need to be removed along with the ICL implant.
ICL is a procedure involving implanting a lens inside the eye to correct refractive errors. LASIK is a laser refractive procedure used on the cornea to correct refractive errors. ICL is a reversible procedure, which means that the lens implanted could be removed or replaced if needed, whereas LASIK results can be amended but the procedure is not reversible.
LASIK surgery is known to cause more dry eye symptoms and in terms of visual outcome, the ICL procedure has better outcomes when correcting high perscriptions (more than 6 dioptres of short-sightedness). Laser refractive surgery is still considered less invasive in comparison to ICL.
