Abstract
Purpose: :
To evaluate the effect of apodized diffractive intraocular lens (IOL) (AcrySof ReSTORE) on frequency doubling technology (FDT - Humphrey Matrix) when compared to the same yellow plataform (AcrySof Natural IQ).
Methods: :
We selected eyes submitted to uncomplicated facoemulsification and IOL implantation (AcrySof ReSTORE and Natural IQ), by the same surgeon, that stated with at least 20/30 uncorrected visual acuity. Previous eye surgery, other eye disease, elevated IOP and glaucoma suspect eyes because of suspect optic discs were excluded. 24-2 full threshold strategy FDT perimetry (Matrix) was performed three months after cataract surgery. Patients were previously trained (30 minutes before the full exam) with the screening Matrix program. We analyzed mean deviation (MD) and pattern standard deviation (PSD) between the two groups, using the t test corrected for interocular correlation.
Results: :
There were 37 eyes of 22 subjects, 17 eyes received the AcrySof ReSTORE IOL and 20 eyes received the AcrySof Natural IQ. They were 15 women and 7 men and their age varied from 41 to 81 years old. Pupillary diameter was similar in both groups (P=.20). Comparing the group that received AcrySof ReSTORE and AcrySof Natural IQ, there was no statistically significant difference in MD (P =.77), neither in PSD values (P=.20)
Conclusions: :
When interpreting FDT Matrix, apodized diffractive IOL (AcrySof ReSTORE) did not seem to cause any substantive interference in its results.
