INTRODUCTION:
Aphakia without sufficient capsular support can be due to many reasons such as intraoperative complications during phacoemulsification,intracapsular cataract extraction (ICCE),ocular trauma, and lens dislocation caused by various reasons (e.g., Marfan Syndrome, congenital or secondary weakness of zonules, etc.). The implantation of an ICIOL is a time-saving surgery with low intrusiveness, and the operation technique is much easier than the implantation of a SF-IOL. The implantation of a retropupillary IC-IOL combines the advantages of a PCIOL and a short operation time as well as an easy operation technique;
MATERIALS AND METHODS:
It is a retrospective study of 47 eyes, undergone primary implantation of posterior chamber iris claw lens(PCICIOL) in 23eyes and sulcus fixated IOL(SFIOL) in 11eyes and secondary implantation of PCICIOL in 8 eyes and SFIOL in 5 eyes.
Causes of primary implantation included- Marfans syndrome, isolated traumatic subluxation/dislocation of lens.
Causes of secondary implantation included- Operative complications, ECCE or ICCE with lens subluxation
Setting- single surgeon, tertiary eye care centre, Assam, India.
Outcome measures were the visual acuity at 1 month post operative and 1 year post operative, the surgical time, and the postoperative complications.
RESULTS:
Overall, 60% of eyes with primary implantation had va better than 20/40 in both the lens types. 78% pciciol group and 58% SFIOL group in secondary implantation had va better than 20/40. post operative cx included retinal detachment in one case, each of the two lens types in primary implantation group, ovalisation of pupil in pciciol group and dislocated IOL ,which is comparable in both the groups.
CONCLUSION:
Posterior chamber/ Retropupillary Iris claw lens can be safely used as an alternative to SFIOL.
