  2. Purpose • Cataracts with shallow anterior chamber is a challenge for surgeons, due to lacking space. • Anterior chamber fluctuation may contribute to increase the fragility of the tissues in the anterior chamber. • We looked the added benefits of “Occlusion Controlled Phaco” in cataracts with a shallow chamber.

  3. Methods • Prospective analysis of 12 cases with cataracts of varying density and shallow anterior chambers • Patients anterior chambers 2.0mms ≤ were assigned. • Anterior chambers were measured with immersion A-scan. • All cases were operated with torsional energy with vacuum sensitive longitudinal energy delivery.

  4. Methods • Videoanalysis; • Configurationof incision, • The nucleus removal times, • Amount of energy dispersed, • Amount of fluid used, • Number of surges during nucleus removal were recorded. • Pre and post operative visual acuities and eye pressures , cornealedemaand iris defects were noted.
