Many people find glasses and contact lenses inconvenient and seek alternatives. A modern procedure called SILK (Smooth Incision Lenticule Keratomileusis) offers a solution. This advanced, flapless laser treatment corrects vision by removing a small disc-shaped tissue, called a lenticule, from the cornea. The amount of tissue removed depends on the prescription. Unlike LASIK, which creates a corneal flap, SILK is less invasive. However, it is more expensive, ranging from approximately INR 1.25 lakh to INR 1.75 lakh. SILK provides smoother recovery, less discomfort after surgery, and a lower risk of dry eyes compared to traditional methods. Dr Ikeda Lal, Senior Consultant at Sir Gangaram Hospital, explains that doctors assess factors like refractive error, corneal topography, and thickness to recommend the best procedure. While both surgeries are safe, patients may initially experience some dryness. Research continues to improve these techniques and address age-related vision issues like presbyopia.
Understanding SILK and Its Comparison with LASIK
SILK is a lenticular-based procedure that removes a small tissue layer from the cornea to eliminate the need for glasses. In contrast, LASIK involves creating a corneal flap, lifting it, and reshaping the underlying tissue with a laser before repositioning the flap. LASIK is a time-tested, less expensive method that works for various refractive errors, including cylindrical powers. Visual recovery after LASIK is typically faster for most patients. Choosing between the two depends on factors such as refractive error, corneal topography, and thickness. Doctors evaluate these aspects to determine suitability. Both procedures are safe, though some patients may experience temporary eye dryness. Complications are rare when performed by experienced professionals. Ongoing research aims to enhance these techniques and address near vision correction after age forty.
