to evaluate effect of custom made iol for each pts to evaluate effect of neutralising SA (SPHERICAL ABERATION)OR Q VALUE (ASPHERICITY) of cornea separately and which will perform better.

two group of iol are made at BIOTEC factory india. group one has SA neutralising ability and they are labelled as RC00 TO RC05 depending upon their ability to neutral ize SA of cornea.similarely Q based iol are labelled as RCQ01 to RCQ05 depending upon ability to neutralise asphericity of cornea. 150 Patients bet age of 40 and 60 without any ocular pathology are selected. Routine preoperative investigation with special focus on corneaL SA/QVALUE was done.Routing phaco surgery done. Any intraoperative complication are excluded. IOL are selected to nearest value of SA or Q value.In group one SA correcting iol are implanted either to same value or slight undercorrection of SA. In group two Q based iol are used and iol selected either to same value or slight overcorrection of Q value iol. Follow up on 1/7/30/180 days .BCVA for distance ,near and contrast study were done for each.
In group one(SA based) 70% achieved 6/4 vision and maintained same for six months.they required add of +1.5 to +2.0 for near. In group two (Q based ) 80% achieved 6/4 vision and near add was+2.0. In both group contrast improved by 20%.
Customisation of iol surgery is future for cataract surgery.Q based performed better for distance than SA based. While SA based perform better for near. Both group perform much better than random selection of iol. Selection of iol should be done on basis of Q VALUE or SA VALUE of cornea for excellent post op results and very happy patients.
