When a patient is originally diagnosed with cataracts surgery may not be required. Gradually the cataracts may worsen as the protein build up continues to accumulate on the lens. Patients may notice an increase in dulled vision, colors may appear less bright, and there may be a greater appearance of halos around lights at night. Dr. Khetpal may then recommend the patient undergo cataract surgery.
In cataract surgery, the cloudy, damaged lens in your eye is removed and replaced with what is called an intraocular lens or IOL. The IOL is a clear, artificial lens implant that can both relieve the patient from the dulled vision caused by the cloudy lens, as well as correct the patient’s vision.
Before the surgery we will measure the length of the patient’s eye using what is called an A-scan. Secondly, the curvature of cornea will be measured using a technique called keratometry. Doctor Khetpal will then discuss the various lens options available with the patient. Even if the patient has undergone a LASIK procedure, or other laser procedures, to correct vision they can undergo a cataract surgery. It is important to provide us with the vision correction prescription the patient had before the LASIK procedure so that an accurate IOL prescription can be determined.
Often a cataract surgery is referred to as a “phaco” procedure. This is because the most common procedure to remove a cataract is called “phacoemulsification”. A small incision is made in the side of the cornea and Dr. Khetpal uses a tiny instrument which emits high frequency ultrasound to break up the diseased lens and carefully remove it. After the old lens is removed the new IOL (replacement lens) is inserted. This allows light to properly pass through and focus on the retina. After the IOL is in place Dr. Khetpal closes the incision made on the cornea and stitches it. After the surgery a clear, plastic protective shield is placed over your eye.
At Texoma Retina Center our cataract surgeries are done in an operating room as an out-patient procedure meaning the patient is able to go home the same day but will need a driver.
It is vital to apply the prescribed drops and protect your eye by wearing a shield at night. Patients may experience some blurry vision a few days to weeks after the procedure.
As with any medical procedure there are inherent risks with cataract surgeries. These risks can include infection, bleeding, increased intra-ocular pressure, swelling and retina and in very rare cases vision loss. Please discuss any concerns you have with Dr. Khetpal.
