Treatment Options for Myopia
When it comes to treating myopia, corrective lenses are considered the most straightforward solution. These lenses work by refocusing light in a way that ensures it reaches the retina instead of falling short in front of it. To determine the most suitable lenses for a patient, optometrists use a specialized device known as a phoropter. The prescription for these lenses is typically indicated by a negative number, signifying the presence of myopia. For instance, a prescription of -3.00 D indicates mild myopia.
Can Surgery Help?
When it comes to correcting myopia in adults, surgery can be a viable option. However, it’s important to note that these procedures can only be performed once the eyesight has stabilized, which typically occurs in adulthood. There are two common types of surgery that are used to address myopia: laser-assisted in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK).
Both LASIK and PRK work by reshaping the cornea through the removal of layers of tissue. This reshaping process helps to focus light on the retina, improving vision. However, it’s worth noting that there are limitations to the amount of tissue that can be safely removed during surgery. As a result, individuals with high levels of myopia may not be ideal candidates for these procedures.
If surgery is not a suitable option, an alternative approach is to have a doctor place phakic intraocular lenses (IOLs) inside the eye. These lenses provide a permanent solution by assisting with the focusing of light. This option may be more appropriate for individuals with high myopia who are not suitable candidates for LASIK or PRK surgery.
