Phakic IOL is a special kind of intraocular lens that is implanted surgically into the eye to augment nearsightedness or myopia. The eye’s natural lens is left untouched during the process. If the IOL is implanted after cataract surgery has already been performed, which involves removal of the natural lens, it is called pseudophakic.
Usually made of plastic or silicone, the IOL is inserted through an incision made in the front of the eye. It is positioned just behind or in front of the iris.
The IOL corrects refractive errors or imperfections in the eye’s focusing ability. These errors cause blurred or out-of-focus images. If you suffer from nearsightedness, you find it difficult to see objects far from you, than objects near you.
Addressing Common Phakic Lens Questions
A phakic lens is an intraocular lens (IOL) that is implanted into the eye while preserving the natural lens. Unlike cataract surgery where the natural lens is removed, phakic lenses are used to correct refractive errors such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.
Phakic lenses work by adding an additional lens to the eye's optical system to correct refractive errors. The lens is surgically implanted either in front of or behind the iris, while the natural lens remains in place. The phakic lens helps to focus light correctly onto the retina, improving vision.
Phakic lenses are typically recommended for individuals with moderate to severe refractive errors who are not suitable candidates for other vision correction procedures like LASIK or PRK. Good candidates for phakic lenses generally have stable vision, sufficient anterior chamber depth, and healthy eyes without significant ocular conditions.
The phakic lens implantation procedure is typically performed under local anesthesia. The surgeon makes a small incision on the cornea and inserts the folded phakic lens into the eye through the incision. The lens is then positioned either in front of or behind the iris. The procedure usually takes about 15-30 minutes per eye.
Phakic lens implantation is considered a permanent procedure. However, in certain situations where necessary or upon medical recommendation, the lens can be removed or exchanged. It's important to discuss the potential risks, benefits, and long-term implications with your surgeon before undergoing the procedure.
Phakic lens implantation, like any surgical procedure, carries risks and potential complications. These may include infection, inflammation, increased intraocular pressure, corneal edema, cataract formation, glare or halos, and residual refractive errors. It's crucial to have a detailed discussion with your surgeon to understand the potential risks and benefits specific to your case.
Recovery time after phakic lens implantation can vary among individuals. Most people experience improved vision within a few days to a week after the procedure, but it may take several weeks for complete stabilization. Your surgeon will provide specific post-operative instructions, including the use of prescribed eye drops and any restrictions on activities during the healing period.
Phakic lens implantation is designed to significantly reduce or eliminate the need for glasses or contact lenses. Many patients achieve improved uncorrected vision after the procedure. However, the outcome can vary depending on individual factors, and some patients may still require minimal correction or reading glasses for specific tasks. Your surgeon can provide a realistic expectation of your visual outcome during the consultation.
