Contoura Vision Surgery

Are you considering getting rid of your eyeglasses? Are you searching for surgical options for vision correction? Look no further. Contoura vision surgery is the latest advancement in laser vision correction that can help you see clearly without eyeglasses or contact lenses. 

Contoura vision surgery , also called topography-guided LASIK surgery, is an advanced and personalized type of LASIK vision correction surgery. 

LASIK or ‘laser-assisted in situ keratomileusis’ is an eye surgery that employs lasers to correct refractive errors and improve vision. When someone has a refractive error, their eye is unable to refract or bend light correctly, which results in unclear image formation and blurred vision. LASIK corrects the refractive error by reshaping the cornea so that it can refract light properly and the eye can form a clear image. 

However, Contoura vision surgery or topography-guided LASIK has an advanced feature when compared to traditional LASIK. Apart from changing the shape of the cornea, it also addresses abnormalities affecting the surface texture of the cornea. Another advancement of Contoura vision surgery over traditional LASIK is that while LASIK surgery treats only the pupillary axis of the eye, Contoura vision surgery helps treat the visual axis of the eye, which is the natural axis at which eyes see.

Contoura vision surgery can map 22,000 unique elevation points on the cornea (the clear, dome-shaped front surface of the eye). This information is analyzed and sent to a computer, which directs the laser beam during surgery to correct the minute variations of curvature at each point. 

This surgery removes corneal irregularities and creates an optically flawless smooth corneal surface, thereby enhancing visual quality and preventing side effects such as glare and halos at night.

Contoura vision surgery customizes the laser treatment to the unique surface shape of each eye. Thus, the corrected vision resulting from this surgery is of higher quality. This surgery can eliminate the need for eyeglasses for vision correction.

Contoura vision surgery is recommended for vision problems resulting from the following refractive errors:

• Myopia: Commonly known as nearsightedness, in this condition you can clearly see objects that are close by (nearsighted) but objects farther away appear unclear. Myopia is the result of a refractive error caused by the eye being too long or oval-shaped or the curve of the cornea being too steep. 
• Hyperopia: Commonly called farsightedness, in this condition your near vision is unclear whereas you can clearly see objects far away (farsighted). Hyperopia is a result of a refractive error caused by the cornea being too flat or the eyeball being too short.
• Astigmatism: This condition causes you to have blurred vision at all distances, whether near or far. Astigmatism is the result of a refractive error caused by the surface of the cornea or the lens being egg- or oval-shaped, instead of perfectly curved. 

Contour vision surgery is also recommended for patients who may not be suitable candidates for LASIK surgery due to their abnormal corneal surfaces.

• Before the surgery, your eye surgeon will schedule a discussion with you about the procedure, its benefits and risks, your expectations, and any questions you may have. Your medical and surgical history, including your current medication, is also discussed. 
• The surgeon then performs a detailed eye examination, followed by pre-surgical tests such as the corneal topography test to check the curvature and thickness of the cornea. The results of this test help in deciding if you need to undergo Contoura vision surgery. 
• The surgeon also performs a test called dilated fundoscopy, which is the examination of the retina once your pupils are dilated. It helps diagnose conditions and identify retinal risk factors for potential vision loss. 
• Any retinal pathologies such as thinning, holes, or tears detected during the retinal evaluation are treated before the surgery using a laser. 

• On the day of the surgery, a topolyzer, an advanced corneal mapping device, is used to take topographic scans of your eye. With this information, the surgeon creates a detailed map of your cornea's surface, along with identifying corneal irregularities.
• Before the surgery, you are made to lie on your back and may be given medication to help you relax.
• The surgeon adds numbing drops to your eyes and places a suction ring and eyelid speculum in the eye to prevent blinking and adjust eye movement. 
• The surgeon then creates a thin flap in the cornea using bladeless femtosecond technology and lifts and folds the flap back to access the cornea. 
• While you focus and fix your eye on a target point of light, the surgeon reshapes parts of the cornea using a topography-guided excimer laser. Information received from the topolyzer about your corneal surface is used to guide the laser.
• A small amount of corneal tissue is removed with each pulse of the laser beam. Contoura vision surgery involves computerized eye movement tracking so that when the laser is used, it delivers pulses with higher accuracy.
• The surgeon ends the surgery by putting the corneal flap back in place. The flap begins reattaching immediately and does not usually need sutures.

• You may be observed for 30 minutes and discharged after the surgery. 
• Before you go home, the surgeon will explain any medications you need to take and post-operative precautions you need to follow. They will also discuss your schedule for follow-up appointments. 
• The surgeon may also prescribe eye drops to prevent infection and facilitate the healing process. 
• You can expect to feel some discomfort for about 4 hours after the procedure. 
• You may also need to use artificial tears to combat dry eyes for 2 weeks after the surgery. 
• You may be asked to wear protective eye shields while you recover at home. 
• The recovery time for Contoura vision surgery is about one day. You can expect clear vision without eyeglasses or contact lenses the next morning after the procedure.

Contoura vision surgery has the following benefits or advantages:

• Enhanced vision sharpness and quality
• Bladeless, painless, and stitchless procedure
• No injections or bandaging involved
• No need for hospitalization
• Less damage to eye tissues
• Faster healing and recovery

As is the case with any other surgery, Contoura vision surgery is also associated with certain risks and potential complications. These include:

• Dry eyes
• Infection
• Bleeding and swelling
• Under-correction or overcorrection of vision
• Complications with the corneal flap
• Requirement of further treatment due to regression of vision with time
