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

Criteria

Inclusion Criteria:

  • Pupil dilation equal or greater to 7 mm after mydriasis.
  • Patients undergoing cataract surgery for the first eye.
  • Visual prognosis equal or greater to 6/12.

Exclusion Criteria:

  • Patients with history of ocular pathology, glaucoma, uveitis, high myopia, PEX, or corneal pathology.
  • Patients with traumatic, subluxated and posterior polar cataract.
  • Patients who had previously ocular surgery in the past 6 months prior to the screening visit.
  • Patients with diabetic retinopathy.
  • Patients who are not suitable for follow-up visits.
  • Patients with Fuchs' Dystrophy, Macular Degeneration, Ocular Surface Disease that will interfere with normal recovery.
  • Any patients with significant intra-operative complications will be removed from the overall analysis of the results. All patient data should still be recorded, even if from the "excluded" patient group.
