Objective To determine whether texturing the optic edge of the intraocular lens
reduces photic symptoms in patients with square-edged acrylic intraocular
lense implants.
Methods Sixty patients underwent routine phacoemulsification performed by a
single surgeon and were prospectively randomized to receive either the standard
AcrySof MA30 intraocular lens (Alcon Laboratories, Ft Worth, Tex) (group 1)
or an MA30 intraocular lens with a textured optic edge (group 2). Patients
were seen at 1 month by an independent observer who was masked to treatment
groups. A questionnaire on photic symptoms was completed, and attempts were
made to elicit symptoms under mesopic and photopic conditions.
Results At 1 month postoperatively, 20 (67%) of 30 patients in group 1 noticed
symptoms compared with 4 (13%) of 30 patients in group 2 (P<.001). The mean duration of symptoms was 3.5 weeks in group 1
and 1 week in group 2 (P = .01). By provocative testing
under photopic conditions, symptoms could be elicited in 26 patients (87%)
in group 1 and 6 (20%) in group 2. No patients in either group were symptomatic
at 3 months postoperatively. Under mesopic conditions, symptoms could be elicited
in 27 patients (90%) in group 1 and 11 (37%) in group 2. There was no relationship
between the incidence of symptoms and the degree of intraocular lens–rhexis
contact.
Conclusion Photic phenomena can be significantly reduced by texturing the edge
of a square-edged profile AcrySof intraocular lens.
