Abstract Details

Purpose:

To compare the final incision size and wound structure after the intraocular lens (IOL) implantation from the 2.2mm transconjunctival sclerocorneal wound between the use of a motorized injector and of a manual injector.

Setting:

Kobe Kaisei Hospital, Japan

Methods:

Prospective randomized clinical trial. All patients had phacoemulsification and received Acrysof SN60WF IOL implantation from the 2.2mm transconjunctival sclerocorneal wound using a D cartridge. Patients were randomly devided into two groups as follows: Group A, a motorized injector at first speed (4.4mm/s) were used for the IOL implantation, and Group M, a manual injector were used for the IOL implantation. The change in wound size, need for sclerocorneal hydration, surgically induced astigmatism (SIA), and optical coherence tomography (OCT) findings of the wound structure were analyzed.

Results:

77eyes were enrolled (Group A: 33 eyes, Group M: 34 eyes). The change in wound size was significantly larger in Group M (Group A: 0.03±0.05mm, Group M: 0.09±0.06mm, p<0.01). The SIA 1 day after the surgery were 0.38±0.25D in Group A and 0.44±0.17D in Group M (p=0.30). No patients needed a sclerocorneal hydration. OCT finding demonstrated no significant difference about the wound damage between two groups.

Conclusions:

The use of motorized injector may contribute to the less surgical invasion to the surgical wound. FINANCIAL INTEREST: NONE
