What is Myopia?
Myopia, also known as nearsightedness, is one of the most common refractive anomalies in the world. Its main feature is that you have trouble seeing objects clearly at a distance while at the same time having no problems seeing objects up close. Given the rise of myopia, especially in children and young adults, the question of whether it is curable becomes more and more topical.
Treatment
Although myopia cannot be permanently cured, various treatments can help check and in some cases reduce the rate at which it advances. These therapies aim at high myopia and glaucoma complications, and aim at minimizing the use of the corrective lenses.
The most widespread therapies for myopia are using prescription glasses or contact lenses. These optical devices right the refractive problem and give individuals the ability to see clearly at all distances. Nevertheless, these spectacles do not deal with the root of the myopia problem or stop its development.
Alternatively, there is a method known as orthokeratology, also called ortho-k or corneal reshaping therapy. This non-surgical method employs the use of rigid gas permeable contact lenses, which are worn overnight and work to reshape the cornea temporarily. Ortho-k lenses achieve this by delicately flattening the cornea to correct refractive errors, thus improving vision without glasses during the daytime. In spite of the fact that orthokeratology is efficient in slowing down myopia progression, it necessitates strict daily use of lenses and regular eye care professional following-up.
Also, there are drug technologies, for example, atropine eye drops, that have been proven to slow down the regression of myopia mainly in children. The atropine eye drops relax the focusing muscles of the eye by tightening the eyeball, which is a primary cause of myopia progression. Conversely, the long-term effects and optimal dosage of atropine therapy are unclear as more research is conducted.
In the last few years, the refractive surgery technology has come up with alternative treatments to correct myopia. Procedures like LASIK (laser-assisted in situ keratomileusis) and PRK (photorefractive keratectomy) utilize the laser technology to remodel the cornea which subsequently eliminates the need for eyeglasses or contact lenses. Although these operations may produce excellent results visually, they are not for everyone and the patient should be aware of possible risks and side effects.
Besides, lifestyle changes for instance spending less time outside and reducing near work activities could be protective against myopia worsening in particularly children. The precise pathways through which the environmental factors affect myopia remain unclear, but they point to the contribution of environmental factors in the development and management of myopia.
Conclusion
In sum, while myopia cannot be permanently treated, it can be controlled by utilizing various treatment options which can help slow down its progression. Early detection and intervention are the keys to limiting the effect of myopia on eye health and vision. People who wear glasses to correct their myopia should make an appointment with an eye doctor to decide on the best treatment option for their particular case.
