Technology offers less invasive, gentler treatment
Laser-guided surgery for cataracts can be a fairly new technology, but it’s quickly becoming the most preferred way to treat cataracts and astigmatism.
Lasers have many perks over conventional surgery, ideal patients.
For something, though it’s effective, conventional surgery for cataracts is much more invasive. In conventional surgery, we use hand-held blades to spread out the eye. Then, we utilize a probe that vibrates at ultrasonic speed to fragment a person's eye’s lens making sure that we can eliminate it and compensate for an artificial plastic lens.
Using a laser, we accomplish a number of these same tasks — however with computer guidance. It’s considerably more precise as opposed to human hand alone.
It’s also much gentler on the attention than ultrasound. That’s particularly crucial for certain patients with sensitive eyes.
For example, patients with Fuchs’ Corneal Dystrophy risk swollen corneas after surgery. Laser-guided surgery lessens the risk weighed against conventional surgery.
One procedure treats two conditions
Laser surgery has an additional benefit: a chance to correct some types of astigmatism.
Astigmatism is definitely an irregularity of a persons vision’s curvature that may lead to vision distortion. With laser-guided surgery, we can easily correct astigmatism concurrently as the cataract surgery. This makes it lower the probability that you will need glasses following procedure.
But you'll find things you should know about before undergoing laser-guided surgery for cataracts. First, it’s a two-part operation. Even following laser portion ends, you need to go into the operating room for the remainder in the procedure, where we physically get rid of the lens and put it back with a man-made lens.
Second, we never try this type of laser means of astigmatism alone. We only get it done in conjunction with cataract surgery. There are ways to correct astigmatism without cataract surgery, but that’s a new laser procedure altogether, like LASIK (Laser-Assisted In Situ Keratomileusis).
Are that you candidate?
Laser surgery for cataracts has some limitations. For example, the laser can’t correct all astigmatism.
Astigmatism may be either regular or irregular. If the cornea looks much more a football, the laser corrects it wonderfully. If the astigmatism is irregular and possesses more of an egg shape, the laser doesn’t do nearly as good a career. There are some situations where we can't correct the astigmatism in any respect, either with laser or conventional surgery. The patient just has to put on contacts or glasses.
Those who've had LASIK should probably avoid this action. LASIK results in a flap of tissue inside cornea, when the laser fires it, it might change the characteristics of their flap and affect a person’s eyesight.
Patients are becoming additional demanding about achieving good vision after cataract surgery. In using a technology with your a high level of predictability, we expect to keep getting a lot better at giving people more precise, corrected vision.
