What is cataract and what is Cataract surgery?
A cataract is a common condition in which the normally clear lens of the eye becomes progressively cloudy. When light passes through a clear lens, the light can focus to a point, creating a clear view. When light passes through a cataract, it gets distorted, creating a blurred view. Vision with cataract is may be fuzzy and colors might be muted. These visual disturbances due to cataract are progressive and when they become bothersome or limit your daily activities, it is time to consider treatment.
Treatment for cataract involves surgery to remove the cataract and replace it with an intraocular lens implant. It is most common surgical procedure in the world and is considered to be extremely successful and safe.
What is LASER Cataract surgery?
Many of the steps of traditional cataract surgery are performed using handheld tools. Now, they can be done with the precision of a laser. Using the CATALYS PRECISION LASER SYSTEM, your surgeon can offer you unprecedented accuracy and customization in your cataract surgery procedure.
The CATALYS can be used to create a circular opening for accessing and removing the cataract. Clinical studies have shown this opening to be 10 times more accurate when performed with CATALYS, than which is achievable by hand. CATALYS then softens and breaks up the hard cataract into tiny pieces, allowing for gentle and easier cataract removal.
Depending upon your pre-operative vision, and desired visual result, your surgeon may recommend a tailored treatment plan that could include creating ultra-precise laser incisions in the cornea and a specific implant type, (Multifocal lens for near and far vision). This tailored treatment may reduce your need for glasses or contact lenses after surgery.
How is Laser Cataract Surgery different from Traditional Cataract Surgery ?
Ageing is the most common cause. With age, proteins of the eye lens get altered and opacified leading toIn traditional cataract surgery, incisions in the cornea are made using handheld blades to access the cataract. An opening is then created manually with the use of a surgical instrument, in the lens capsule of the eye that holds the cataract. The goal in these steps is to make the corneal incisions precise and the opening in the capsule, as circular as possible, in the right location, and sized to fit the replacement lens.
With CATALYS, the corneal incisions can be made with exceptional precision and accuracy. Moreover, the surgeon can create the circular opening with the exact intended size, shape and location using the precision of the laser.
The surgeon can also use the laser to break up and soften a hard cataract. Softening the lens with CATALYS facilitates the removal of cataract more gently and with significantly less energy than is used in traditional manual cataract surgery. This gentle low energy approach reduces inflammation and help speed visual recovery.
Depending upon your preoperative vision, and desired visual result, your surgeon may recommend a tailored treatment plan that could include creating ultra-precise incisions in the cornea(Astigmatic Keratotomy, Limbal relaxing incisions) and a specific lens implant type(Multifocal lens for far and near vision). This tailored treatment may reduce your need for glasses or contact lenses after surgery.
What are the Benefits of Laser Cataract Surgery ?
- A highly customized treatment using advanced 3D imaging
- A treatment with little or no discomfort
- A more precise treatment
- A gentler and easier cataract removal
- Generally, a more rapid visual recovery due to reduced inflammation
- The opportunity to receive tailored treatment with advanced technology multifocal lenses, which may reduce the need for glasses or contact lenses after surgery.
Am I A Suitable Candidate For Laser Cataract Surgery?
Most patients are generally suitable for laser cataract surgery. Your doctor and his / her counselling staff will discuss your candidacy in more detail during your cataract evaluation exam.
How Long Has The Procedure Been Performed ?
Thousands of procedures have been successfully performed using the CATALYS Precision Laser System, and lasers have been used in eye procedures for decades. CATALYS represents the new standard in precision laser cataract surgery and was FDA cleared in 2011.
What Should I Expect On The Day Of Surgery?
You will be called to the hospital two hours prior to the surgery for dilatation of pupil and preparation of the eye to be operated. Under topical anaesthesia, first the laser treatment of the eye will be performed. This is followed by removal of the cataract using phacoemulsification and implantation of the intraocular implant.
How Does The Laser Work?What Is It Doing To My Eye?
Every eye has unique size and shape. Prior to treatment, the CATALYS Laser Precision System scans your eye making 3D map of relevant structures. This process enables your surgeon to make highly customized treatment plan that is tailored for your eye. The laser then focuses light to create precise incisions exactly where intended. The laser makes incisions in a matter of seconds. You should expect little or no discomfort.
What Will I Feel?
You can expect little or no discomfort during the treatment. During the laser portion, patients describe seeing kaleidoscope of lights and slight pressure only.
How Long Does The Procedure Take?
You can expect the total time in the hospital to be 3 to 4 hours at our centre. You will be in the procedure room for about 15 minutes.
What Should I Expect For Recovery?
Normally you will be able to see after 10-15 minutes after the surgery, but vision may be hazy. Most patients see well at 1st post-operative day , but in some cases for example, hard and mature cataracts, it may take 2 to 3 days for full visual recovery
