Title	Comparison of effective lens position between standard phaco and FLACS
Abstract Nr.	2078

Purpose	Two groups of patients where compared . the first group represented standard phacoemulsification . The second group is operated on by Femto laser assisted Phaco (FLACS). The same IOL platform was used in the two groups. Pre and post op anatomical measurements were taken in order to compare between groups. This study was initiated to see if there was a difference in anterior segment parameters such as the Effective Lens Position ( ELP) between both groups. ELP is related directly to the A constant of the IOL.
Methods	The two groups were operated by the same Surgeon. Laser measurements of the anterior segment parameters by optical biometer and scheimphlug topography and OCT anterior segment analyser were taken pre and postoperatively.
Results	Standard phaco : AD mean 2,397 ACD mean 2,937 , ELP internal : mean 4,004 , difference AD post-pre : mean 1,607 , ELP epith-iol : mean 4,544 Femto Assisted Cataract Surgery AD mean 2,763 ACD mean 3,313 , ELP internal : mean 4,4775 , difference AD post-pre : mean 1,7145, ELP epith-iol : mean 5,0412 Pentacam measurements results, Standard phaco : ACD Post-Pre : mean 1,607 Femto Assisted Cataract Surgery : ACD Post-Pre : mean 1,728 The two groups showed no statistical difference in anterior segment parameters pre and postoperatively.
Conclusion	This study showed no statistical difference between the standard phaco and the FLACS group in ELP. As such the ELP can be ruled out as parameter to explain the difference in A-constant to be used in IOL calculation for both groups.
