Presently surgical treatment of choise in a 22 year male with – 10D myopia is
**Core Concept**
For a 22-year-old male with -10D myopia, the surgical treatment should aim to correct the refractive error and improve visual acuity. This involves understanding the principles of refractive surgery and the most suitable procedures for high myopia.
**Why the Correct Answer is Right**
The most appropriate surgical treatment for high myopia like -10D is LASIK (Laser-Assisted In Situ Keratomileusis) with a femtosecond laser. This procedure uses a thin flap created in the cornea to allow for precise reshaping of the underlying tissue, correcting the refractive error. The femtosecond laser creates a precise and safe flap, reducing complications and improving outcomes.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because PRK (Photorefractive Keratectomy) is a traditional refractive surgery that involves removing the outer layer of the cornea and reshaping the underlying tissue with an excimer laser. While PRK can correct high myopia, it's generally considered less effective and more painful than LASIK.
**Option B:** This option is incorrect because LASEK (Laser-Assisted Subepithelial Keratomileusis) is a variation of LASIK that uses a thin layer of epithelium to create a flap. However, it's not the preferred choice for high myopia like -10D, as it can be more prone to complications.
**Option D:** This option is incorrect because Implantable Collamer Lens (ICL) is a type of refractive surgery that involves implanting a lens inside the eye. While ICL can correct high myopia, it's generally considered for patients with high levels of myopia who are not good candidates for LASIK.
**Clinical Pearl / High-Yield Fact**
Remember that the choice of surgical treatment for high myopia depends on the individual patient's needs and characteristics. A thorough evaluation of the patient's corneal thickness, pupil size, and other factors is essential to determine the most suitable procedure.
**Correct Answer: C. LASIK with a femtosecond laser**
