Abstract Details

Purpose:

To compare the cumulative dissipated energy( CDE) and post op endothelial cell density(ECD) with and without the use of miLoop for hard cataracts in eyes undergoing phacoemulsification

Setting:

Nethradhama Superspeciality Eye Hospital, Bangalore

Methods:

This prospective study included 50 eyes of 50 patients with nuclear sclerosis grade 4 and above,undergoing phacoemulsification using the Centurion system( Alcon surgicals). Eyes were randomised into two groups -group 1 phaco only and group 2 phaco with miLoop, wherein the miLoop instrument was used to assist in fragmentation of the hard brown nucleus. All surgeries were performed by a single experienced surgeon using the same energy and fluidics parameters. Intra-operatively, the mean CDE value was noted at the end of the surgery. Post-operatively at day 1 and 6 months, the mean ECD was compared between both the groups.

Results:

Pre operatively, both groups were matched in terms of mean age, grade of cataract and ECD( p=0.05 for all parameters).Intra-operatively, the phaco  group had a mean CDE value of 28( range 22-45) , whereas the phaco+miLoop group had a CDE value of 18( range 15-26)( p=0.040)At 1 month, the mean ECD in phaco only group was 2125+/-124 cells versus 2356+/- 143 suggesting a significantly higher ECD loss in phaco only group( p=0.02). No eye in either group had intra op complications such as PCR, ZD or bag loss, or post op issues such as irreversible corneal oedema or endothelial decompenstion.

Conclusions:

miLoop may be a useful tool to assist in the management of hard brown cataracts and may lead to less ECD loss compared to routine phacoemulsification done in such cases.
