Lens surgery is a type of eye surgery used specifically for the treatment of eye diseases such as cataracts. A cataract is a clouding of the eye’s natural lens and can significantly affect vision. This allows the patient to see clearly again.
How is Lens Surgery Performed?
Lens surgery is an operation usually performed for the treatment of cataracts. Cataract is a condition in which the natural lens in the eye loses its transparency and becomes cloudy. Cataract surgery is the most effective method to restore the quality of vision. This operation is usually performed under local anesthesia and the patient can be discharged the same day. This surgical procedure is performed in the following ways:
- The patient is usually locally anesthetized with eye drops before the surgical procedure. Sedation is usually also given so that the patient relaxes but remains awake.
- Working under a microscope, the surgeon makes a very small incision in the front surface of the eye.
- The cataractous lens is usually broken up and removed using ultrasound energy.
- Once the natural lens is removed, it is usually replaced with a foldable artificial lens. The new lens is usually folded through the incision and unfolded after it is placed inside the eye.
- The incision usually does not require stitches and heals on its own. However, in some cases one or two stitches may be needed.
- After the operation, the patient’s eye is usually covered with a bandage or protective goggles. The patient will use antibiotics and anti-inflammatory eye drops for a certain period of time.
Lens Surgery Risks
Like any surgical procedure, lens surgery carries some risks and complications. The risks of lens surgery are generally as follows:
- Infection of the eye may occur after surgery.
- In rare cases, the retina may be damaged.
- Intraocular pressure may increase after surgery, which may increase the risk of glaucoma.
- Surgery may cause or worsen astigmatism.
- Capsule formation can occur over time around the artificial lens that replaces the lens, which can blur vision.
- Some patients may experience discomfort in conditions such as bright lights and night driving.
- As with any surgical procedure, the healing process can cause complications.
- Although extremely rare, serious complications can lead to vision loss.
- Anesthesia has its own risks, especially for the elderly or people with chronic health conditions.
Recovery After Lens Surgery
Lens surgery is a commonly used procedure for the treatment of eye conditions, especially cataract surgery. Depending on the type of lens surgery and the general health of the patient, the recovery process may vary.
There may be some mild pain or discomfort in the first few days. The quality of vision may not improve immediately. There may be blurriness, double vision or sensitivity to light. Antibiotics and anti-inflammatory drops are usually given in the first days after surgery.
Regular eye examinations may be required within a few days and then for several weeks following surgery. Heavy exercise and activities that may put the eye at risk should be avoided.
