The couching procedure is another name for which intervention?

• A. Trans-corneal reduction 'couching' procedure
• B. Intracapsular lens extraction
• C. Enucleation
• D. Medical management with topical carbonic anhydrase inhibitors

Answer: (A)

Couching is an ancient surgical approach to glaucoma where the lens is displaced through the cornea to relieve blockage and open a path for aqueous humor to drain. This is described as a trans-corneal reduction procedure because the manipulation is done via the cornea to push the lens aside rather than removing it. It lowers intraocular pressure by altering the lens’s position to improve drainage. This is the best answer because it directly names the technique as a trans-corneal reduction, which matches the historical and clinical description of couching. It isn’t a cataract extraction where the lens is removed, nor enucleation which would mean removing the entire eye, and it isn’t medical therapy with topical carbonic anhydrase inhibitors, which are drugs rather than a surgical displacement.
