Overview
Brief Summary
This study is a comparison of the surgical techniques and postoperative outcome between the two intrascleral IOL fixation techniques: Yamane technique versus the 4-flanged technique.
The main objectives are postoperative lens tilt, duration of surgery, intra- and postoperative complication rates and scleral integrity around the flanges.

Eligibility Criteria
Inclusion Criteria
- •- Necessity for IOL (re)fixation in the absence of capsular support
- •willing to give informed consent and follow-up the duration of study
Exclusion Criteria
- •Anatomical or other contraindications for suture less IOL fixation, such as presence of a trabeculectomy bleb or scleromalacia
- •active inflammatory diseases of the eye
Outcomes
Primary Outcomes
IOL tilt
Time Frame: 3 years
The postoperative intra ocular lens tilt in degree measured by an anterior segment optical coherence tomography device (Casia 2, Tommy, Japan)
IOL decentration
Time Frame: 3 years
The postoperative intra ocular lens decentration in millimetres measured by an anterior segment optical coherence tomography device (Casia 2, Tommy, Japan)
Secondary Outcomes
- Best corrected visual outcome(12 weeks)
- Flange erosion and intrusion(3 years)
