Abstract Details

Purpose:

To evaluate the Tecnis Reusable and Rayner disposable IOL Injection systems in terms of ease of insertion, time spent and complications occurred during IOL loading and implantation in the capsular bag.

Setting:

Eye Department Central Park Medical College &WAPDA Teaching Hospital Complex 210 Feroz Pur Road Lahore Pakistan.

Methods:

Prospective study of 25 eyes each implanted with aspheric Rayner Superflex and Abbot Tecnis Aspheric ZCB00 foldable IOLs from January 2011 to Dec 2011. Routine phacoemulsification was performed in all the eyes. Both types of IOLs were implanted using their own recommended cartridges and insertion devices provided by respective manufacturers i.e. disposable device in case of Rayner and disposable cartridge with reusable plunger in Tecnis group. Lens Insertion time (LIT) was calculated from opening of the IOL and its cartridge /injector to placement and final positioning of its haptics in the fornices of capsular bag. Other criteria used to analyze, included optic haptic catch/damage, overshooting, use of excessive force during intraocular delivery, stress marks on IOL surface, and difficulty in unfolding etc.

Results:

All 25 eyes in each group had smooth Phaco and intra bag injection of IOLs with their recommended IOL Insertion System. LIT were ±85 seconds in Rayner and ±95seconds in Tecnis group. Mild to moderate overshooting was noted in three cases in Tecnis group and none in Rayner group. One IOL got stuck and needed repositioning in the cartridge in Rayner group. It took a little time for Tecnis to open up in the bag as compared to Rayner IOL.

Conclusions:

Both IOL Injection systems were found to be safe and effective. However it is stressed that proper positioning in the cartridge i.e. extended haptics in case of Rayner and fetal position haptics in case of Tecnis is the key to success in respective groups.
