Laser Eye Surgery for High Myopia: What You Need to Know - Ophthalmology

More Info

---

When considering laser eye surgery for high myopia, especially with a prescription nearing 1000 degrees, there are several important factors to take into account. Laser eye surgery, such as LASIK or PRK, is designed to reshape the cornea to improve vision, but it is not suitable for everyone, particularly those with very high degrees of myopia or other eye conditions.


Eligibility for Laser Eye Surgery
1. Degree of Myopia: Most laser eye surgery procedures can effectively treat myopia up to around -12.00 diopters, but this can vary based on individual circumstances, including corneal thickness and overall eye health. For prescriptions nearing -10.00 or -12.00 diopters, a thorough evaluation by an eye care professional is crucial to determine if you are a suitable candidate.

2. Age Considerations: Generally, candidates for laser eye surgery should be at least 18 years old. This is because the eyes are still developing during the teenage years, and performing surgery before the prescription stabilizes can lead to less predictable results. If you are under 18 and your myopia is progressing rapidly, it is advisable to consult with an eye care specialist who can monitor your condition and discuss potential interventions, such as orthokeratology or atropine eye drops, which may help slow the progression of myopia.

3. Corneal Thickness: A critical factor in determining eligibility for laser surgery is the thickness of your cornea. If your cornea is too thin, there may not be enough tissue to safely reshape it, which can increase the risk of complications. A comprehensive eye exam will assess this.

4. Overall Eye Health: Conditions such as dry eye syndrome, glaucoma, or retinal issues can disqualify you from laser surgery. A thorough examination will help identify any underlying issues that need to be addressed before considering surgery.


Risks and Considerations
1. Surgical Risks: While laser eye surgery is generally safe, it does carry risks, including dry eyes, glare, halos, and in rare cases, vision loss. The likelihood of these complications increases with higher degrees of myopia.

2. Postoperative Care: After surgery, patients must adhere to specific postoperative care instructions to ensure proper healing and minimize complications. This includes avoiding water in the eyes, not rubbing the eyes, and attending follow-up appointments.

3. Long-term Effects: It’s essential to understand that while laser surgery can significantly reduce dependence on glasses or contact lenses, it may not eliminate the need for them entirely, especially as you age. Conditions like presbyopia (difficulty focusing on close objects) will still occur, and you may need reading glasses in the future.


Alternatives to Consider
If you are not a suitable candidate for laser surgery, there are alternative options available:
1. Contact Lenses: Specialized contact lenses, such as scleral lenses, can provide comfort and improved vision for those with high myopia.

2. Orthokeratology: This involves wearing specially designed contact lenses overnight to temporarily reshape the cornea, which can help control myopia progression.

3. Intraocular Lenses (IOLs): For very high prescriptions, some patients may benefit from phakic intraocular lenses, which are implanted in the eye without removing the natural lens.


Conclusion
In summary, while laser eye surgery can be a viable option for many individuals with high myopia, it is crucial to undergo a comprehensive evaluation by an eye care professional to determine your eligibility. Given your age and the degree of your myopia, it is essential to monitor your condition closely and explore all available options. If you have concerns about the rapid progression of your myopia, discussing these with an eye specialist can provide you with tailored advice and potential treatment plans.
