Purpose
Scleral-fixation of IOL(SF-IOL) is done when adequate capsular bag support is not present for implantation of a PCIOL. Such a situation can arise due to pre-existing conditions such as subluxation or dislocation of the lens or due to complications during a cataract surgery. Different methods of SFIOL have been described but most of them are meticulous and time consuming. CMT-flex is an innovative IOL that reduces extra ocular manipulation of haptics, is less time consuming and is easier to implant. SFIOL has been the area of expertise for posterior segment surgeons, but can CMT-flex turn the tables? We explore the possibility and compare it with other methods of SFIOL and iris supported IOLs.
Setting
The study was performed in a tertiary care eye charitable eye hospital in the himalayan state of uttarakhand in India. This is a prospective, interventional and comparative case series.
Methods
A prospective analysis of patients requiring scleral fixation of IOL was done. The patients were randomly assigned to three different groups : A- sutured SFIOL, B- Modified yamane technique and C- CMT-flex IOL. Patients with other conditions affecting the visual acuity were excluded. A single surgeon performed the surgeries in India over a period of 1 year. Postoperative best-corrected visual acuity (BCVA), intraoperative and postoperative complications, duration of surgery and time for recovery were studied and compared amongst these groups.
Results
A total of 18 eyes were analysed. The minimum follow-up was 3 months. The majority of eyes experienced an improvement in UDVA after surgery; with more than 90% eyes having Snellen equivalent corrected distance visual acuity of 6/12 or better. The baseline characteristics and final visual outcomes in all the groups were comparable. CMT-flex IOL was superior in terms of lesser intraoperative time, fewer complications and quicker recovery. intraoperative haptic rupture was the most common complication associated with CMT-flex IOL.
Conclusions
Shorter surgical time, lesser rate of complications and shorter learning curve makes CMT-flex an attractive option for when SFIOL is required .
