Outcome Following Phacoemulsification Versus Small Incision Cataract Surgery (SICS)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00821223
Recruitment Status : Completed
First Posted : January 13, 2009
Last Update Posted : May 19, 2010

Iladevi Cataract and IOL Research Center

Brief Summary:

Hypothesis :

Phacoemulsification is superior to SICS with regards to:

  • Immediate unaided high and low contrast visual performance
  • Its impact on quality of life.

Condition or disease Intervention/treatment Phase
Visual Outcomes Quality of Life Procedure: phacoemulsification and SICS Procedure: manual small incision surgery Procedure: phacoemulsification Not Applicable

Detailed Description:

Phacoemulsification procedure

  • Infiniti Vision System with Software 2.03 or higher, OZil handpiece (HP)
  • Anaesthesia: topical
  • Incision: temporal clear corneal 2.2 mm single plane
  • CCC and hydrodissection, sculpting and division using step by step chop in situ and lateral separation, I/A.
  • Single-piece AcrySof IOL (SN60WF) in the bag

SICS procedure

  • Anaesthesia: peribulbar
  • Incision: superior scleral tunnel 6.5 to 7 mm
  • CCC and hydrodissection
  • Nuclear expression: blumenthal technique using anterior chamber maintainer, manual cortical clean-up
  • Single-piece PMMA (MZ60BD) in the bag
