LASIK (Laser-Assisted In Situ Keratomileusis) is a popular surgical procedure used to correct vision problems such as nearsightedness, farsightedness, and astigmatism. It involves using a laser to reshape the cornea, the clear front part of the eye, to improve the way light is focused onto the retina, thus improving vision. LASIK is a relatively quick and painless procedure that can often reduce or eliminate the need for glasses or contact lenses.

LASIK and cataract surgery are two different procedures that address different vision problems. LASIK: - Corrects refractive errors (nearsightedness, farsightedness, astigmatism) by reshaping the cornea - Does not address cataracts Cataract surgery: - Removes the cloudy lens (cataract) and replaces it with an artificial lens (IOL) - Does not correct refractive errors LASIK cannot "cure" cataracts because: - Cataracts are a clouding of the lens, whereas LASIK addresses corneal shape - LASIK does not remove or replace the lens If you have both refractive errors and cataracts, you may need to undergo: 1. Cataract surgery to remove the cloudy lens and implant an IOL 2. LASIK or other refractive surgery to fine-tune any remaining refractive errors Consult an eye doctor or refractive surgeon to determine the best course of treatment for your individual needs.

43:29 Cataract surgery is an operation to remove a cloudy eye lens. The most common type of cataract surgery is phacoemulsification, also known as small-incision cataract surgery: The surgeon makes a small opening in the eye, usually near the outer corner. A probe emits ultrasound waves to break up the cataract's hard core. Another probe uses suction to remove the rest of the cataract material through the same opening.

Sir please answer this one - Ravi kept a book at a distance of 1m from the eyes of his friend Hari. Hari is not able to read anything written in the book. Give reasons for this? As a friend, how you help Hari to solve his problem of vision?

This is case of myopia, u = -∞(healthy) v= 100 cm or 1m Lens formula:- 1/f= 1/v-1/u 1/f= 1/100 - 1/∞ ( 1/∞=0) 1/f= 1/100-0 f = 100 cm P= 100/f(cm) P= 100/100 P= +1D +1D and +vs focal length tells us convex mirror (nature - converging)

LASIK or Lasik, commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hypermetropia, and an actual cure for astigmatism, since it is in the cornea.
