Cataract surgery is a minimally invasive procedure that involves numbing the eyes with anesthesia and then making a tiny incision into which an ultrasonic probe is inserted. The probe breaks up, or emulsifies, the cloudy lens into tiny pieces and then suctions them out of the eye. Once the cloudy lens has been removed, a new artificial lens is implanted into the eye. This lens is known as an intraocular lens (IOL), and is inserted through the same incision that the old lens was removed from.
Surgery usually takes less than 15 minutes to perform and is painless for most patients. After the procedure, a patch is placed over the eye and you will be asked to rest and then go home the very same day. You will need someone to drive you home. For the next few days, you may experience itching, mild discomfort, fluid discharge and sensitivity to light and touch. Your doctor will prescribe eye drops to help the healing process and to reduce the risk of infection.
Cataract surgery can significantly increase your quality of life by giving you the freedom to resume activities you may have had to stop, such as exercising, driving, and reading. According to an article posted by the New York Times, this means cataract surgery could also even prolong your life.
There are several different IOLs available to help each patient achieve the best possible results from cataract surgery. Monofocal lens implants give you distance at far. Toric lens correct for astigmatism and Multifocal IOLs offer full vision correction at near, intermediate and far distances, reducing the need for eyeglasses or contact lenses in most patients.
These choices are discussed in depth at a patients consultation with their surgeon.
Risks and Complications
If left untreated, cataracts will worsen over time and may lead to permanent vision loss or even blindness. It is important to see your eye doctor regularly in order to detect cataracts as early as possible and to plan an effective treatment method.
Although cataract surgery is considered safe, there are certain risks associated with any surgery. Some of these risks may include pain, infection, swelling and bleeding. Most patients undergo this procedure without any complications.
Femtosecond Laser Assisted Cataract Surgery
The newest evolution in cataract surgery – a custom-tailored procedure that’s as unique as your eye itself!
*A technologically-advanced procedure
*Offers a new level of precision and reproducibility.
*Optimizes alignment of capsulotomy and corneal incisions
NTEC offers patients Femtosecond (Femto) Laser Assisted Cataract Surgery. This is a reliable, consistent and predictable method that makes the procedure much more controlled and safe. Your NTEC surgeon can create high precision incisions with a special laser to facilitate the use of premium lens implants.
The Femto Laser is also used to create precise flaps in bladeless LASIK. Femto laser is now used in advanced cataract surgery and makes the procedure completely bladeless. It replaces several manual aspects of cataract surgery, including surgical incisions in the cornea, the circular opening on the lens surface (capsulotomy) and breaking up (fragmentation) of the lens. It can also be used to make incisions in the peripheral cornea to aid the correction of pre-existing astigmatism.
How is Femtosecond Laser Assisted Cataract Surgery Performed?
State-of-the-Art in Positioning Premium IOLs
SMI Surgery Pilot and Microscope Integrated Display provides Integrated Visual Guidance™ to the surgeon during cataract surgery with a consistent real-time eye coordinate system.
Based on anatomical eye features, SMI Surgery Guidance™ automatically registers the patient’s eye diagnostic information to the microscope camera to give a live image which assists the surgeon with a real-time adjusted tracking overlay. The distinctive SMI technology makes ink markers obsolete, optimizes the workflow and ensures reproducible accuracy.
SMI Surgery Guidance™ supports the exact positioning of incision and LRIs, the centering and sizing of the capsulorhexis, and the accurate centering of toric and multifocal intraocular lenses.
Refractive correction services that are offered during cataract surgery can include special-feature intraocular lenses like multifocal and accommodating IOLs, femtosecond laser-assisted cataract surgery, and other specialized diagnostics. These services are an additional cost to patients because they are not deemed medically necessary. Newer innovations for cataract surgery aim to enhance refractive outcomes for patients who are hoping to be independent from glasses or contacts, but at a financial cost.
