Advanced Cataract Surgery
Cataract surgery is one of the most common surgeries performed, and also one of the safest and most effective.
At Imperial Healthcare, we use the most sophisticated, advanced and safe technology and techniques to clear the cloudy lens by gentle ‘phacoemulsification’ surgery requiring only eye drop anesthesia (topical) and without needing any stitches. The combination of a highly accurate lens measurement system (lenstar biometry) and premium intra-ocular lenses allows us to ensure a high percentage of complete spectacle freedom after surgery. So you can achieve clear spectacle-free vision by a 20 minute painless procedure without the use of any needles, injections or stitches. You can usually return home half an hour after the procedure and get back to your usual activities including work within a matter of days. We recognize that this procedure is only required once in your lifetime therefore we ensure that nothing but the best is used to perform this treatment.
Phacoemulsification is a variation of extracapsular cataract extraction, a procedure in which the lens and the front portion of the capsule are removed, by making an incision.
In phacoemulsification cataract surgery, the surgeon makes a very small incision — about 1/8th of an inch — in the white of the eye near the outer edge of the cornea. A small ultrasonic probe is inserted through this opening and, oscillating at 40,000 cycles per minute, is used to break up emulsify the cataract into tiny pieces. The emulsified material is simultaneously suctioned from the eye by the open tip of the same instrument. The hard central core of the cataract is removed first, followed by extraction of the softer, peripheral cortical fibers that make up the remainder of the lens. The front (anterior) section of the lens capsule is removed along with the fragments of the natural lens. The back (posterior) portion of the capsule is left in place to hold and maintain the correct position for the implanted intraocular lenses.
After removal of the cataract, a prescription intraocular lens, or IOL, is permanently implanted in the lens capsule to replace the natural crystalline lens of the eye that was removed during the surgery. This lens is rolled inside a tiny hollow tube and inserted through the same incision that was used to remove the cataract. The folded lens is pushed out of the tube by a tiny plunger and, as it unfolds, is positioned by the surgeon in the center of the lens capsule. The new lens is held in place by microscopic, spring-like wires that are attached to the implant.
Immediately following surgery, the patient is monitored in an outpatient recovery area. The patient is advised to rest for at least 24 hours, until he or she returns to the surgeon’s office for follow-up.
There will be some changes in the eye during recovery. Patients may see dark spots, which should disappear a few weeks after surgery. There also might be some discharge and itching of the eye. Patients may use a warm, moist cloth for 15 minutes at a time for relief and to loosen the matter. Pain and sensitivity to light are also experienced after surgery.
Complications are unlikely, but can occur. Patients may experience spontaneous bleeding from the wound and recurrent inflammation after surgery. Flashing, floaters, and double vision may also occur a few weeks after surgery. Other possible complications are the onset of glaucoma. It is possible that a secondary cataract may develop in the remaining back portion of the capsule. This can occur for as long as one to two years after surgery. YAG capsulotomy, using a laser, is most often used for the secondary cataract.
