Which of the following step is not done during phacoemulsification surgery for cataract?
Ans. is 'd' i.e., Sclerocorneal tunnel Phacoemulsification* It is nothing else but an advancement in the method of doing ECCE. Here the nucleus is converted into pulp or emulsified using high frequency sound waves, and then sucked out of the eye through a small (3.2 mm) incision at sclerocorneal junction. A special foldable IOL is then inserted 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 cortex, (v) Foldable IOL implantation in posterior chamber.* Recovery with phacoemulsification is fastest as incision is very small and no sutures are taken.
