Laser Eye Treatments for Refractive Problems

Medical lasers are important tools for ophthalmologists. Since the first successful eye surgeries using laser light rays, these devices have become ubiquitous in eye clinics. 

Common and Recent Treatments

From successfully treating damaged retinas, people now turn to laser surgery for vision correction. People who depend on eyeglasses or contact lenses due to refractive errors benefit from a laser eye surgery. Examples of refractive errors are myopia or short-sightedness, hyperopia or long-sightedness, and astigmatism.

Laser eye surgery corrects ageing-related vision problems such as presbyopia. This inability to focus on nearby objects can also be corrected with eyeglasses. As an assistive technology, laser also helps in treating cataract, especially since it helps prevent complications common to cataract surgery. 

Common and Special Benefits says different people have different eye problems. For most people, and most kinds of problems, laser eye treatment is more affordable and less time-consuming to complete.  More importantly, without surgically opening the eyes, it can prevent blindness among individuals with certain vision problems.  

For instance, people diagnosed with a detachment of the retina from the eye can become blind without treatment. Laser surgery provides aid by fixing the retina to the back of the eyeball. A laser impulse focused in the small area in the retina makes a scar tissue, which then serves to prevent the retina from coming loose.   

People with diabetic retinopathy can also benefit from this kind of treatment. This condition causes dimming vision due to the blood that leaks into the eye from fragile blood vessels. The surgery closes the abnormal blood vessels, preventing them from causing further damage.

The treatment uses a continuous-wave visible laser light with less than a watt. While it cannot completely prevent blindness, it can delay the progression.

All the eye conditions mentioned above indicate a problem in focusing an image on the retina. A consultation with an eye doctor should tell you whether you can benefit from laser eye surgery or not.
