High Myopia: Glasses Prescription and Laser Surgery Options - Ophthalmology

More Info

---

Understanding high myopia and its implications on vision correction is crucial, especially when considering options like glasses prescriptions and laser surgery. High myopia, defined as a refractive error greater than -6.00 diopters, can lead to various ocular complications, including retinal detachment, macular degeneration, and other vision-threatening conditions.
In your case, you mentioned having a prescription of -1250 diopters while your recent examination showed a measurement of -1175 diopters after dilation. It's not uncommon for there to be slight variations in measurements due to factors such as the testing method, the state of accommodation, or even the time of day. However, if your current glasses prescription allows you to see clearly (1.2 vision), it indicates that your glasses are effectively compensating for your refractive error. The goal of any prescription is to provide the best possible vision, and if you feel secure and comfortable with your current vision, then your prescription is likely appropriate.

Regarding the presence of a "black spot" on your retina, this is a significant concern. It could indicate a retinal tear, detachment, or other serious conditions that require immediate attention. If surgical intervention is necessary to repair the retina, it is essential to discuss the implications of such surgery with your ophthalmologist. Generally, repairing the retina does not preclude you from future laser vision correction; however, the specific type of surgery you may have undergone and the condition of your eye post-surgery will influence your eligibility for laser procedures.

When it comes to laser vision correction options, there are several types, including LASIK, PRK (Photorefractive Keratectomy), and SMILE (Small Incision Lenticule Extraction). Each method has its advantages and considerations:
1. LASIK: This is the most common procedure, where a flap is created in the cornea, and a laser is used to reshape the underlying corneal tissue. It is generally quick and has a fast recovery time. However, it may not be suitable for patients with thin corneas or certain retinal conditions.

2. PRK: In this procedure, the outer layer of the cornea is removed, and the laser is applied directly to the corneal surface. PRK is often recommended for patients with thinner corneas or those who may not be candidates for LASIK. The recovery time is longer compared to LASIK, but it can be a safer option for high myopes.

3. SMILE: This is a newer technique that involves creating a small incision in the cornea to remove a lenticule of tissue, reshaping the cornea without creating a flap. It is less invasive and may have fewer complications related to dry eyes post-surgery.

Before considering any laser surgery, it is crucial to have a thorough evaluation by a qualified ophthalmologist who specializes in high myopia. They will assess the health of your retina, the overall structure of your eye, and your specific refractive error to determine the most suitable option for you.
In conclusion, while your current glasses prescription seems adequate for your vision needs, the presence of a retinal issue necessitates careful monitoring and possibly surgical intervention. After addressing the retinal condition, you can explore laser correction options, but this should be done in consultation with your eye care professional to ensure the best outcomes for your vision and overall eye health. Regular follow-ups and adherence to your ophthalmologist's recommendations are essential in managing high myopia effectively.
