Relationship Between Needle Thickness and Intraocular Hemorrhage in Scleral Fixation of Intraocular Lenses

Purpose: To evaluate the relationship between needle thickness and intraocular hemorrhage in patients who underwent scleral fixation of intraocular lenses. Methods: The records and surgical videos of 44 patients who underwent scleral fixation from January 2002 to December 2005 were reviewed. Only eyes with two-point scleral fixation using a 26-gauge needle and 10-0 polypropylene were included. We checked for intraoperative intraocular hemorrhage that occurred at the time of introducing the needle through the sclera. The cases were divided into those with anterior chamber bleeding, those with mild vitreous hemorrhage less than or equal to grade II, and those with severe vitreous hemorrhage greater than or equal to grade III. Results: Of the 44 eyes, 12 eyes (27.3%) showed intraocular hemorrhage, 10 eyes (22.7%) by 26-gauge needles and 2 eyes (4.5%) by 10-0 Prolene needles (p=0.026). Six eyes (13.6%), 5 by 26-gauge and 1 by 10-0 Prolene needles, suffered anterior chamber bleeding. Four eyes (9.1%), 3 by 26 gauge and 1 by 10-0 Prolene needles, showed mild vitreous hemorrhage, and 2 eyes (4.5%) by 26-gauge needle suffered severe hemorrhage. Conclusions: The incidence of intraocular hemorrhage appears to be lower when thinner needles are used in scleral fixation. J Korean Ophthalmol Soc 2008;49(10):1578-1582
