ABSTRACT

PURPOSE: To compare the effect of an apodized diffractive intraocular lens (IOL) (Acrysof ReSTOR NaturalTM) and its yellow counterpart (Natural IQ TM) on frequency doubling technology (FDT) perimetry results. METHODS: This study included 37 eyes from 22 patients at the "Centro Oftalmológico Tranjan" who had undergone uncomplicated phacoemulsification and intraocular lens implantation (17 Acrysof ReSTOR NaturalTM, 20 Natural IQ TM) performed by the same surgeon, at least three months prior to the study. Patients were subject to frequency doubling technology Matrix Perimeter testing. RESULTS: The patients were between 41 to 79 years old (mean, 70.78 ± 9.83) in the Natural IQ TM and 49 to 81 years old (mean, 67.11± 11.48) in the Acrysof ReSTOR NaturalTM group, and the mean IOP was 13.64 ± 2.02 mmHg in the Natural IQ TM 12.94 ± 1.39 mmHg in the Acrysof ReSTOR NaturalTM group. The mean pupillary diameter under scotopic conditions was 6.63 ± 1.16 mm in the Natural IQ TM group and 7.20 ± 1.8 mm in the Acrysof ReSTOR NaturalTM group (p=0.20). The mean deviation was -1.83 ± 3.46 dB in the Natural IQ TM group and -1.77 ± 3.94 dB in the Acrysof ReSTOR NaturalTM group (p=0.28). The pattern standard deviation was 3.49 ± 0.79 dB in the Natural IQ TM group and 3.20 ± 0.86 dB in the Acrysof ReSTOR NaturalTM group (p=0.27). CONCLUSION: There was no difference in the results of FDT Matrix perimetry in eyes that received apodized diffractive IOLs implant or eyes that received monofocal intraocular lens implant.


OBJETIVO: Comparar o efeito da lente difrativa apodizada (Acrysof ReSTOR NaturalTM) e da lente de mesma plataforma amarela (Natural IQ TM) sobre os resultados da perimetria de dupla frequência (FDT). MÉTODOS: O estudo incluiu 37 olhos de 22 pacientes do Centro Oftalmológico Tranjan que foram submetidos a cirurgia de facoemulsificação e implante de lentes intraoculares (17 Acrysof ReSTOR NaturalTM, 20 Natural IQ TM) sem complicações, realizadas pelo mesmo cirurgião, pelo menos três meses antes do estudo. Pacientes foram submetidos à perimetria FDT Matrix. RESULTADOS: A idade dos pacientes variou de 41 a 79 anos (média, 70,78 ± 9,83) no grupo Natural IQ TM e 49 a 81 anos (média, 67,11± 11,48) no grupo Acrysof ReSTOR NaturalTM , a PIO média foi 13,64 ± 2,02 mmHg no grupo Natural IQ TM e 12,94 ± 1,39 mmHg no grupo Acrysof ReSTOR NaturalTM. O diâmetro pupilar sobre condições escotópicas foi 6,63 ± 1,16 mm no grupo Natural IQ TM e 7,20 ± 1,8 mm no grupo Acrysof ReSTOR NaturalTM (p=0,20). O MD foi de -1,83 ± 3,46 dB no grupo Natural IQ TM e -1,77 ± 3,94 dB no grupo Acrysof ReSTOR NaturalTM (p=0,28). O PSD foi de 3,49 ± 0,79 dB no grupo Natural IQ TM e 3,20 ± 0,86 dB no grupo Acrysof ReSTOR NaturalTM (p=0,27). CONCLUSÃO: Não houve diferenças nos resultados da perimetria com FDT Matrix em olhos que receberam implante de lentes intraoculares difrativas apodizadas ou olhos que receberam LIOs monofocais.
