**Question:** Laser capsulotomy is done for -

A. Cataract surgery
B. Glaucoma surgery
C. Keratoplasty
D. Macular hole surgery

**Core Concept:**
Laser capsulotomy is a surgical procedure used in various ophthalmic procedures to create a circular opening in the posterior capsule of the eye, which is a thin, transparent membrane that surrounds the lens. This procedure is performed to address specific eye conditions.

**Why the Correct Answer is Right:**
Laser capsulotomy is the right answer because it is a common application in cataract surgery. In cataract surgery, a laser is used to create a capsulotomy to remove the opaque, dense lens (cataract) and replace it with an artificial lens (intraocular lens or IOL). This helps restore the eye's ability to focus light properly on the retina, improving vision.

**Why Each Wrong Option is Incorrect:**

A. Cataract surgery is the primary use of laser capsulotomy, making option A incorrect as it is not the only application.
B. While laser capsulotomy is used in glaucoma surgery, it is not the primary purpose of this procedure, making option B incorrect.
C. Laser capsulotomy is not performed for keratoplasty, which involves replacing the corneal tissue due to corneal disease or injury.
D. Macular hole surgery is a separate procedure used to treat macular holes, not related to laser capsulotomy.

**Clinical Pearl:**
Laser capsulotomy is a valuable tool in cataract surgery, allowing surgeons to create a clear pathway for the IOL to be inserted, improving visual acuity for patients suffering from cataracts. Understanding the various eye conditions for which laser capsulotomy is used is essential for ophthalmologists and other medical professionals treating eye disorders.
