Since not everyone is suitable for laser intervention, the phakic lens implant can provide a solution for those higher myopes, up to -16.5D, and for those who have a thin cornea.
About Phakic lens
The phakic lens is inserted underneath the cornea and is like a very small contact lens. Along with your original lens it directs the light on the retina, correcting shortsightedness. The lens is placed in the front part of the eye and it will remain there for as long as you need it.
Am I eligible?
You are eligible for Phakic lens implantation if:
- Your myopia is between-6.0D and -16.5D
- You are at least 21 years old
- Your vision did not change for a period of 1 year
- If you have no glaucoma
- If no one in your immediate family suffers from glaucoma
- If you do not have diabetes
- If you have no retinal disease
- If your fundus is in good condition
The surgery process
What happens to me during the surgery?
Your doctor will first create a small incision on the cornea. To insert the phakic lens only a small incision is required, there is generally no need for stiching the wound. The frontal part of the eye is filled with thick fluid, which protects the rear surface of the cornea. Then, using a special syringe the Phakic lens is inserted. Once the lens is in its place we remove the fluid and antibiotic drops are added into the eye.
Risks and Complications
Implanting the phakic lens is a surgical procedure and as such, it does carry some possible risks. Be sure to discuss the risks associated with the implant with your doctor before choosing to have the surgery.
Surgery risks include reactions to medicines and vision changes. Common side effects include:
- Scratchiness of the eye
- Sensitivity to light
These risks are rare and may be outweighed by the potential benefits of restoring your vision.
- Retinal detachment
- Increase in eye pressure (glaucoma)
- Corneal haze
- Cataract formation
- Surgical reintervention
- Loss of 2 or more lines of best corrected visual acuity
- Loss of endothelial cell density
For most patients the vision improvement is immediate, but it usually takes 2-4 weeks for stabilization of vision.
