In phakic intraocular lens (IOL) implantation, an IOL is placed inside the eye, but the patient's natural lens is not removed. The lens can be placed in front of or behind the iris, or it can be fixed to it.
Phakic lens implants are a safe and effective option for patients with high myopia (good near vision but poor distance vision) or thin corneas unsuitable for laser eye surgery. Unlike refractive lens exchange, the eye's natural focusing ability is preserved because the natural lens is not altered, and the procedure is reversible.
Phakic intraocular lens (IOL) procedures are most often performed on healthy patients with high levels of myopia who have not yet developed presbyopia and who have no other eye disease; no abnormalities of the iris, pupil, or cornea; and no history of retinal detachment. The phakic IOL is an alternative to refractive lens exchange for people with high levels of myopia because there is a reduced risk of retinal detachment. At Clínica Nivaria, we answer the frequently asked questions our specialists encounter in medical consultations:
What are the potential benefits of phakic intraocular lens implantation?
Among the possible benefits we can mention:
- Good to excellent distance vision without glasses or contact lenses.
- Phakic intraocular lenses are removable (by the specialist).
- Reduction of the risk of glare, halos, or low-light problems that can result from high-intensity laser treatments.
- The natural lens is not removed, which means that the eye's ability to focus near objects is preserved in patients under 40 years of age.
What are the types of phakic intraocular lenses?
Especially useful for people under 45 with significant myopia, phakic intraocular lenses offer a permanent solution without removing the eye's natural lens. The FDA has approved two types of phakic intraocular lenses, and at Clínica Nivaria , after a thorough patient evaluation, our specialists determine the best option for each individual.
- Visian ICL: Known as a “posterior chamber” ICL, Visian is placed behind the iris, the colored part of the eye and vault, above the natural lens. Made from a biocompatible material called Collamer®, Visian lenses complement the eye’s natural chemistry, ensuring a comfortable experience and minimal risk of dry eye syndrome. These lenses also offer astigmatism correction.
- Verisyse: This "anterior chamber" lens is placed in front of the iris, rather than behind it. Made from a medical-grade polymer, its one-piece design facilitates implantation. This lens is used less frequently but may be offered in certain circumstances.
Like LASIK, the phakic intraocular lens implantation procedure is brief. Most patients without corneal astigmatism can expect 20/40 vision or better after implantation.
What should I expect on the day of surgery?
Phakic intraocular lens implantation is an outpatient procedure that typically takes between 15 and 30 minutes. It is usually performed on both eyes at the same time, but you can choose to have it done one eye at a time if you prefer.
Before the procedure, you will be given eye drops to dilate your eyes. You will also receive intravenous anesthesia to help you relax. A small incision is made in your cornea, and the phakic intraocular lens is inserted. The incision is self-sealing, so there are usually no stitches. You will need someone to drive you home after the surgery.
What should I expect during recovery and postoperative care?
The day after your surgery, you will come for a visit to our clinic in Santa Cruz de Tenerife to ensure you are recovering properly. Some patients experience blurred vision the day after surgery, while others can already see clearly; each patient heals differently.
Your vision should improve within a few days. For the first four to seven days after phakic intraocular lens implantation, you should avoid lifting heavy objects or bending over. After the first week, you can resume most of your normal activities, but you should avoid heavy lifting and swimming for the first month after surgery.
