How Phakic Lenses Correct Severe Myopia and Astigmatism?

Vision problems like severe myopia (nearsightedness) and astigmatism can significantly affect daily life, making even simple tasks like reading signs or driving difficult. While traditional solutions such as glasses and contact lenses offer temporary relief, many individuals seek long-term vision correction. One of the most advanced and effective solutions available today is phakic lens implantation.
At Devine Meditech, we aim to provide innovative eye care solutions, and phakic lenses are among the most reliable options for patients with high refractive errors.

How Phakic Lenses Correct Severe Myopia and Astigmatism?

What Are Phakic Lenses?

Phakic lenses, also known as Implantable Collamer Lenses (ICL), are specially designed intraocular lenses that are implanted inside the eye without removing the natural lens. Unlike cataract surgery, where the natural lens is replaced, phakic lenses work alongside your eye’s natural structure to improve vision. These lenses are typically placed either in front of or just behind the iris, depending on the type and patient’s eye condition.

How Do Phakic Lenses Correct Severe Myopia?

Severe myopia occurs when the eye is too long or the cornea is too curved, causing light to focus in front of the retina instead of directly on it. This results in blurred distance vision.
Phakic lenses correct this by altering how light enters the eye. Once implanted, the lens bends (refracts) incoming light so that it focuses accurately on the retina. This significantly improves clarity and allows patients to see distant objects clearly without glasses.
Unlike LASIK, which reshapes the cornea, phakic lenses do not remove corneal tissue. This makes them especially suitable for patients with very high myopia or thin corneas.

How Do They Treat Astigmatism?

Astigmatism is caused by an irregularly shaped cornea or lens, leading to distorted or blurred vision at all distances. Special toric phakic lenses are designed to correct this condition. These lenses have different powers in different meridians, allowing them to compensate for the uneven curvature of the cornea. Once positioned correctly inside the eye, they align with the astigmatism axis and provide sharp, well-focused vision.

Who Is an Ideal Candidate?

Phakic lenses are ideal for individuals who:
Have severe myopia (usually beyond -8.00 diopters)
Have astigmatism along with high refractive error
Are not suitable candidates for LASIK or PRK
Have stable vision for at least one year
Have healthy eyes without significant retinal issues
A comprehensive eye examination is essential to determine eligibility.

The Procedure: What to Expect

Phakic lens implantation is a quick and minimally invasive procedure, usually completed within 15–30 minutes per eye.
The eye is numbed using anesthetic drops
A small incision is made in the cornea
The folded lens is inserted and positioned correctly
The incision heals naturally without stitches
Most patients experience improved vision within a few days, with minimal discomfort.

Benefits of Phakic Lenses

Phakic lenses offer several advantages over other vision correction methods:
High accuracy: Ideal for correcting extreme refractive errors
Reversible procedure: The lens can be removed or replaced if needed
Preserves corneal structure: No removal of corneal tissue
Quick recovery: Fast visual improvement
Excellent visual quality: Sharp and natural vision

Are There Any Risks?

Like any surgical procedure, phakic lens implantation carries some risks, including infection, increased eye pressure, or glare/halos at night. However, with advanced technology and proper post-operative care, these risks are minimal. Choosing an experienced provider like Devine Meditech ensures safety, precision, and optimal outcomes.

Conclusion

Phakic lenses have revolutionized the way severe myopia and astigmatism are treated. They provide a safe, effective, and long-lasting solution for individuals who are not suitable for traditional laser procedures. If you are struggling with high power vision problems and want freedom from glasses or contact lenses, phakic lenses could be the ideal solution. Consult with experts at Devine Meditech to explore your options and take the first step toward clearer vision.
