Abstract Details

Purpose:

Evaluate and compare incision enlargement as well as ingress of trypan blue from the ocular surface into the anterior chamber following implantation of a foldable hydrophobic acrylic intraocular lens (IOL) through a 2.2mm clear corneal incision(CCI) using one automated and two manual injector systems

Setting:

Iladevi Cataract & IOL Research Centre, Raghudeep Eye Hospital,

Methods:

Randomized clinical trial in120 eyes(120 patients)undergoing microcoaxial phacoemulsification through a 2.2mm CCI randomized to three groups depending on IOL injector used:Group I(n=40),where automated motorized injector(Autosert®) used;Group II(n=40),where a plunger type injector(Royale)used;Group III(n=40),screw type injector(Monarch III)used.Incision widths were measured before and after implantation of a foldable,single-piece aspheric hydrophobic acrylic IOL using D cartridge.Following IOL implantation and stromal hydration,trypan blue 0.0125% was applied over the conjunctival surface,and ingress compared.Architectural features of CCIs were evaluated using anterior segment OCT(AS-OCT) on postoperative day 1,1week and 1month

Results:

Ongoing study,results of 60 eyes presented,results will be updated.Incision enlargement from end of phacoemulsification to IOL implantation:Group I(n=19):0.07+0.05, Group II(n=18):0.16+0.05,Group III(23):0.22+0.04;difference being statistically significant(P=0.03).Incision enlargement was greatest with Monarch III injector,followed by Royale,and Autosert.Trypan blue concentration into anterior chamber was(log units):GroupI=1.97+0.45,Group II=1.78+0.48,Group III=2.16+0.38;difference not statistically significant(P=0.48).No difference in descemet’s detachment,incision gaping and loss of coaptation between groups at any followup(P>0.05)

Conclusions:

All injectors allowed smooth IOL implantation through a 2.2mm incision;incision enlargement was least using automated injector
