Phakic Intraocular Lens Application

Phakic IOLs have revolutionized the field of refractive surgery, providing a viable option for individuals with high myopia and high astigmatism who are not suitable candidates for laser refractive correction. Their ability to provide exceptional visual results, combined with the advantages of protection and adjustability, make them a viable choice for individuals seeking long-term freedom.

High myopia: Phakic IOLs can effectively correct severe myopia, even beyond the limits of laser refractive surgery. They provide exceptional visual acuity, reducing dependence on glasses or contact lenses.
High astigmatism: Phakic IOLs can also correct significant astigmatism by compensating for corneal irregularities. They improve visual quality and reduce distortion caused by astigmatism.

High predictability and accuracy: Phakic IOLs provide precise and predictable vision correction, delivering excellent visual results.
Preservation of the natural lens: Unlike cataract surgery, which involves removal of the lens, Phakic IOLs preserve the eye’s natural lens, maintaining its ability to accommodate.

Reversible and adjustable: Phakic IOLs can be removed or replaced as needed, allowing for adjustments or future upgrades in lens technology.

It is important to consider several criteria when assessing a patient’s suitability for phakic intraocular lens (IOL) implantation. These criteria include:

Refractive error: Phakic IOLs are typically used to correct moderate to high-grade refractive errors such as nearsightedness (myopia), farsightedness (hyperopia) or astigmatism.

Stable refraction: The patient’s refractive error must be stable for at least six months to a year, indicating that their prescription has not changed significantly.

Corneal integrity: The cornea must be healthy, free of significant irregularities and have sufficient thickness to support the phakic IOL.

Anterior chamber depth: Sufficient anterior chamber depth is required to accommodate the phakic IOL without causing contact with other structures within the eye.

Endothelial cell count: The patient’s corneal endothelial cell count should be within normal limits to ensure the long-term health of the cornea after phakic IOL implantation.

Pupil size: Adequate pupil size is necessary to minimize the risk of glare and other visual disturbances associated with phakic IOLs.

Age: Phakic IOLs are generally recommended for patients over a certain minimum age (usually 18 or 21 years) to ensure ocular maturity.

Absence of other ocular diseases: The presence of significant ocular diseases, such as glaucoma or retinal disorders, may affect eligibility for phakic IOL implantation.

It is very important to consult an ophthalmologist or refractive surgeon who can comprehensively assess the patient’s individual circumstances and determine the suitability of phakic IOLs as a vision correction option.

Phakic intraocular lenses (IOLs) are generally safe and effective, but as with any surgical procedure, there are potential complications that can occur. Here are some of the possible complications associated with phakic IOL implantation:

Infection: In rare cases, an infection can develop in the eye after surgery, which can lead to inflammation and potential vision loss. If an infection occurs, prompt treatment with antibiotics is essential.

Endothelial cell damage: The implantation process or the presence of a phakic IOL can cause damage to the corneal endothelial cells, which are responsible for maintaining corneal clarity. If a significant number of endothelial cells are lost, it can lead to corneal edema and reduced visual acuity.

Cataract formation: It is a very rare complication. Phakic IOLs do not prevent the natural aging process of the eye and over time some patients may develop cataracts. Cataracts cause the eye’s natural lens to become cloudy, which may require additional surgery to remove the cataract and potentially replace the phakic IOL.

Glaucoma: In some cases, phakic IOL implantation may increase the risk of developing glaucoma, a condition characterized by increased intraocular pressure that can damage the optic nerve. Regular monitoring of intraocular pressure is essential after surgery.

Glare or halos: Some patients may experience persistent glare, halos or other visual disturbances, especially in low light conditions. These symptoms can be uncomfortable but are usually mild and tend to improve over time.

Infection: Inflammation of the eye can occur after phakic IOL implantation and requires the use of anti-inflammatory medications to control it. Most cases of inflammation resolve with appropriate treatment.

It is very important for patients considering phakic IOL implantation to discuss these potential complications and individual risk factors with an ophthalmologist or refractive surgeon. They can provide a comprehensive assessment of the benefits and risks and help determine the most appropriate vision correction option for each patient.
