Hard Cataract Phacoemulsification Using Torsional Ultrasound (Ozil TM) With and Without Intelligent Phacoemulsification (IP)

Jeewan Titiyal

Purpose: To evaluate IP during phacoemulsification using OzilTM in hard Cataract.

Methods: 120 eyes (nuclear sclerosis grades IV-VI) underwent phacoemulsification by a single surgeon using OzilTM without IP in group 1(60 eyes) and with IP in group 2 (60 eyes) with Uniform phaco and IP parameters for both the groups. Crater and chop technique was performed all cases. Cumulative dissipated energy (CDE), ultrasound (U\S) total time and surgical ease were noted. First day status of cornea and specular counts were compared pre and at 4 weeks.

Results: Use of IP resulted in lower CDEs (37.19%) and shorter total U\S times (33.62%), With IP, surgical ease was greater due to prevention of clogging of the phacoemulsification tip. Wound burn was not noted in any case. The first day post operative cornea with visible central Descemet's folds was observed in (9 eyes) 15 % of eyes in Ozil as compared to (3eyes) 05% in IP group. There was no difference in the average pre and post specular counts in both the groups

Conclusions: In hard cataracts Ozil IP enables faster and effective phacoemulsification.
