Phacoemulsification incision is at ?
Ans. is 'a' i.e., Sclero-corneal junction In phacoemulsification very small 3 cmm incision is taken at the sclerocorneal junction. Phacoemulsification It is nothing else but an advancement in the method of doing ECCE. Here the nucleus is conveed into pulp or emulsified using high frequency sound waves, and then sucked out of the eye through a small (3.2 mm) incision. A special foldable IOL is then inseed into the posterior chamber through the same incision. ECCE by phacoemulsification with foldable posterior chamber IOL is the procedure of choice for cataract. The steps in phacoemulsification include :(i) Corneoscleral incision, (ii) Continuous curvilinear capsulorrhexis, (iii) Hydrodissection and hydrodelineation (iv) Emulsification and aspiration of nucleus and then coex, and (v) Foldable IOL implantation in posterior chamber. Recovery with phacoemulsification is fastest as incision is very small and no sutures are taken.
