Can Laser Surgery Reduce My High Myopia and Astigmatism? - Ophthalmology

Laser surgery, particularly procedures like LASIK (Laser-Assisted In Situ Keratomileusis) and PRK (Photorefractive Keratectomy), can be effective options for correcting high myopia (nearsightedness) and astigmatism. However, whether you are a suitable candidate for these procedures depends on several factors, including the severity of your refractive error, the thickness of your cornea, and your overall eye health.

In your case, with a myopia of -7.25 diopters and astigmatism of -1.25 diopters, laser surgery could potentially reduce your dependence on glasses or contact lenses. Most laser eye surgeries are designed to correct myopia up to about -12.00 diopters, and astigmatism can also be treated effectively. However, the specific outcomes can vary from person to person.


How Laser Surgery Works
Laser surgery reshapes the cornea, the clear front part of the eye, to allow light to focus more accurately on the retina. In LASIK, a flap is created in the cornea, and the underlying tissue is reshaped using a laser. In PRK, the outer layer of the cornea is removed, and the laser is applied directly to the surface. Both methods aim to improve vision by altering the curvature of the cornea.


Considerations for High Myopia and Astigmatism
1. Corneal Thickness: One of the critical factors in determining candidacy for laser surgery is the thickness of your cornea. If your cornea is too thin, there may not be enough tissue to reshape, which could increase the risk of complications.

2. Stability of Prescription: Your prescription should be stable for at least a year before considering surgery. If your vision has been changing frequently, it may be advisable to wait until it stabilizes.

3. Age: Generally, candidates should be at least 18 years old, as vision can continue to change during adolescence.

4. Overall Eye Health: Conditions such as cataracts, glaucoma, or severe dry eye can disqualify you from laser surgery. A comprehensive eye exam will help determine your eligibility.


Costs of Laser Surgery
The cost of laser eye surgery can vary widely depending on the location, the surgeon's experience, and the technology used. On average, LASIK can range from $2,000 to $3,000 per eye in the United States. This cost often includes pre-operative evaluations, the surgery itself, and post-operative follow-up visits. It's essential to check if your insurance covers any part of the procedure, as many do not cover elective surgeries.


Risks and Side Effects
While laser surgery is generally safe, there are potential risks and side effects, including:
- Dry eyes
- Glare, halos, or double vision
- Undercorrection or overcorrection of vision
- Flap complications (in LASIK)
- Regression of vision over time
Most side effects are temporary and resolve within a few weeks to months. However, it's crucial to discuss these risks with your surgeon to make an informed decision.


Conclusion
In summary, laser surgery could be a viable option for reducing your high myopia and astigmatism. A thorough evaluation by an eye care professional specializing in refractive surgery is essential to determine your candidacy and discuss the potential benefits and risks. If you decide to proceed, ensure that you choose a reputable clinic with experienced surgeons to maximize your chances of a successful outcome.
