Wearing glasses is not something that everyone prefers. Perhaps more people would prefer to avoid wearing them due to self-consciousness about their appearance or even discomfort than those who would willingly wear the so-called 'contraption.' In other words, wearing glasses is uncool for many people. However, whether we like it or not, many of us must wear glasses for medical reasons and for better eyesight for everyday functioning. Despite the fact that there is a wide variety of frames and lenses available on the market today, most people would avoid wearing spectacles if at all possible. And, for some, contact lenses eliminate the need to constantly wear the ostensibly unwieldy glasses. discomfort at some point. So, one viable option for obtaining permanent freedom from glasses is to undergo Lasik surgery.
How glasses can help our eyes
correcting our eyes' refractive issues. These refractive issues typically include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Light rays passing through the cornea, the outermost front surface of the eye and lens, are not refracted or bent properly onto the retina, which is responsible for sending signals to the brain via the optic nerve, under these conditions. As a result, our vision is blurry. The image becomes focused in front of the retina in nearsightedness, and behind the retina in farsightedness. At the same time, astigmatism occurs when light is refracted in different directions due to the uneven shape of the cornea, distorting our vision.What glasses do is allow light rays to be properly bent onto the most appropriate spot on the retina, allowing us to focus better and see objects more clearly.
How Lasik surgery can be used as an alternative
Those who truly want to avoid wearing glasses can opt for Lasik surgery. Lasik is an abbreviation for Laser-assisted in situ Keratomileusis. The ophthalmologist uses a specialised laser to change the shape and curvature of the cornea, resulting in better light refraction and thus better focus and eyesight. With advances in Lasik technology such as Wavefront-guided Lasik and the use of a femtosecond laser, the procedure provides better visual quality than glasses.
Who should not have Lasik surgery?
At the same time, not everyone should or is able to consider Lasik surgery. Those who have specific cornea-related issues, such as having a thin or uneven cornea, a cone-shaped cornea, or corneal abrasions, should avoid it. In fact, as a prerequisite for this surgery, the cornea must be thick and healthy. Those with frequently changing refractive errors or high levels of such errors should also avoid it. Furthermore, those with cataracts, glaucoma, persistent dry eyes, or diabetes should not consider this option. If pregnant women or those under the age of 18 are thinking about having this surgery, they should reconsider.
There are a few side effects involved.
Although this is a nearly painless procedure with no stitches or bandages, it does have some side effects. For example, scratchy eyes, halos around images, glares, increased sensitivity to light, and bruises are all possible side effects. While most people's side effects are temporary, they rarely become permanent. It can also cause vision loss in severe cases. However, in experienced surgical hands and with the proper equipment, Lasik is still one of the safest surgical procedures on any part of the human body.
Precautions to be taken before surgery
Before surgery, the expert ophthalmologist would review the patient's ocular history, measure refractive errors, corneal thickness, and pupil size, and assess overall eye health. Patients must also discontinue wearing rigid gas-permeable contact lenses three weeks before the test and other contact lenses one week before the test.
As a result, glasses-skeptics, who are in large numbers, do not have to continue wearing their glasses for the rest of their lives. Lasik surgery is a relatively effective and widely available procedure for them.
