Slow IOL injection affects corneal wound structure, compared to fast IOL insertion.

Slow IOL injection affects corneal wound structure, compared to fast IOL insertion.

The prospective randomized clinical trial. Headed by Dr Masayuki Ouchi, Ouchi Eye Clinic and the Department of Ophthalmology, Kyoto Prefectural University of Medicine, Kyoto, Japan, enrolled 80 eyes that underwent phacoemulsification and IOL implantation using a screw-plunger injector.

All patients were randomized into two equal groups. Group F underwent fast IOL insertion and Group S experienced slow IOL insertion. The team compared change in wound-size preoperatively/postoperatively, need for corneal hydration, surgically induced astigmatism (SIA) and optical coherence tomography (OCT) results of the corneal wound structure.

It was discovered that wound size changes were significantly larger in Group S and the OCT results were more prominent. Corneal hydration was needed in 11 eyes in Group F and 40 in Group S.
