An iris fixated phakic IOL is a lens implanted in front of the natural crystalline lens to correct refractive errors. The lens attaches to the mid peripheral iris using fixation points similar to enclavation claws. This approach preserves the natural lens while adding refractive power. It is often used for high myopia or astigmatism when laser procedures are not suitable.

The natural lens stays in place behind it. Proper centration helps maintain high quality vision once healing occurs.
These lenses suit people with high refractive errors, thin corneas, or prescriptions outside the laser correction range. Candidates must have healthy iris tissue and adequate anterior chamber depth. Surgeons confirm measurements before recommending surgery. People seeking reversible refractive correction may also consider this option.
The lenses provide stable optical correction without altering the corneal surface. They deliver clear vision for many high prescriptions. Because the natural lens remains intact, accommodation is preserved until presbyopia develops. Reversibility is another advantage.
An iris-fixated phakic IOL is a lens placed inside the eye while your natural lens stays in place. Long-term checkups matter to monitor eye pressure, corneal health, and lens stability. Keep track of night glare, halos, or changes in clarity, since those can signal that something needs review. If symptoms start suddenly or vision drops fast, contact your eye surgeon promptly.
They are long lasting but can be removed or exchanged if necessary.
They mainly correct distance vision. Reading glasses or other options may be needed later in life.
Proper spacing prevents contact. Surgeons evaluate the chamber depth to maintain safety.
Some people experience halos or glare, especially with larger pupils. Lens sizing and centration help manage this.
