Implantation of phakic intraocular lenses: an advanced alternative to correct refractive errors


Phakic intraocular lenses are incorporated into the eye's optical system, preserving its natural ability to focus.

Phakic intraocular lenses have significantly improved the correction of refractive errors (myopia, hyperopia, and astigmatism) by providing a valuable option to improve vision without requiring removal of the eye's natural lens. Unlike cataract surgery, where the lens is replaced, these lenses are integrated into the eye's optical system, preserving its natural ability to focus.

The main purpose of this procedure is to address and attempt to correct refractive errors. Essentially, these lenses optimize the way light enters the eye, enabling precise focus on the retina and providing clear vision.

This treatment serves as a valuable alternative for individuals who may not be suitable candidates for other refractive surgeries like LASIK, PRK, or SMILE. It proves particularly advantageous for those with high refractive errors, severe dry eyes, or thin corneas. Conditions such as high myopia, hyperopia and astigmatism may indicate performing this procedure.

This treatment is recommended for individuals with stable prescriptions, typically over 18 years of age. The decision to undergo this procedure should be guided by an expert ophthalmologist capable of comprehensively evaluating the patient's ocular conditions and visual needs.

The phakic intraocular lens implantation procedure is typically performed on an outpatient basis, often under topical or local anaesthesia. The results of this procedure are highly satisfactory in terms of visual correction, with most patients experiencing significant improvement in uncorrected vision within a few weeks, often reducing or eliminating dependence on glasses or contact lenses.

While the results are generally long-lasting, it's important to note that the surgery is corrective rather than curative. Therefore, changes in prescription may occur over time, potentially necessitating additional adjustments in the future.
