Brief Summary:

Senile cataract is managed by cataract extraction and intra-ocular lens (IOL) implantation. The purpose of this study is to evaluate the safety and efficacy of the SeeLens AF, an acrylic hydrophilic aspheric IOL. This lens was designed to reduce vision aberrations and secondary cataract formation rate.

Preoperative evaluation: Best corrected visual acuity, refraction, comprehensive slit lamp examination and biometry.

Surgical procedure: Cataract surgery using a clear corneal incision (1.8mm to2.4mm), phacoemulsification and implantation of the SeeLens AF to the capsular bag. IOL implantation parameters will be evaluated by the surgeon.

Postoperative follow up: Best corrected visual acuity, uncorrected visual acuity, refraction and comprehensive slit lamp examinations up to 3 months after surgery.

Intervention Details:
  • Device: SeeLens AF intra-ocular lens
    the SeeLens AF is an acrylic hydrophilic C shaped haptics intra-ocular lens, designed for implantation in the lenticular capsular bag or the sulcus during cataract surgery.
    Other Name: aspheric SeeLens

Primary Outcome Measures :
  1. Best corrected visual acuity 3 months after SeeLens AF implantation [ Time Frame: 3 months ]

Secondary Outcome Measures :
  1. Complications related to SeeLens AF implantation during cataract surgery. [ Time Frame: 3 months ]
  2. Postoperative severe intra-ocular inflammation or infection [ Time Frame: 3 months ]
  3. Prediction of ocular refraction after cataract surgery with Seelens AF implantation [ Time Frame: 3 months ]
