To compare the health economic parameter and clinical outcome of Phacoemulsification with small incision cataract surgery (SICS)

Condition Intervention
Cataract Procedure: Phacoemulsification cataract extraction surgery Procedure: Small incision cataract surgery

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Treatment

Primary Outcome Measures:
  • Posterior Capsule Opacification Evaluation [ Time Frame: 12 months after surgery ]
    The number of subjects with Posterior Capsular Opacification (PCO) for 12 months post-surgery of the study eye. PCO may occur after cataract surgery and is caused by residual lens epithelial cells that remain in the capsular bag after surgery and undergo proliferation, migration, and fibrous metaplasia. PCO was evaluated via slit lamp. A lower PCO rate is better.

Secondary Outcome Measures:
  • Corneal Astigmatism [ Time Frame: 3 months after surgery ]
    Analysis of corneal astigmatism 12 months after surgery using Orbscan Topography. A lower corneal astigmatism value is better.

Enrollment: 106
