Effect of yellow-tinted intraocular lens on standard automated perimetry and short wavelength automated perimetry in patients with glaucoma

ABSTRACT

To investigate the effect of cataract surgery and yellow-tinted intraocular lens [IOLs] implantation on perimetry indices of short-wavelength automated perimetry [SWAP] and standard automated perimetry [SAP] testing in patients with coexisting cataract and glaucoma. In this prospective comparative case series, phacoemulsification with implantation of yellow-tinted Acrysof Natural IOL was performed in 16 eyes of 16 patients with visually significant cataract [best-corrected visual acuity [VA] better than 20/120] and mild to moderate glaucoma. Pre- and postoperative values for VA and for perimetry indices including mean deviation [MD], pattern standard deviation [PSD], and foveal threshold [FT] from both SAP and SWAP testing were compared. Postoperative VA improved significantly after cataract surgery and yellow-tinted IOL implantation [P < 0.001]. After cataract extraction and IOL implantation, MD and FT on SWAP testing improved significantly [P = 0.001]; however, there was no statistically significant change with SAP testing between the pre- and postoperative perimetry indices. There was no statistically significant change in PSD with either SAP or SWAP testing postoperatively. The differences between pre- and postoperative values for all perimetry indices under study were not significant when comparing SAP with SWAP tests, except for MD which had improved statistically significantly in SWAP testing [P = 0.03]. In mild to moderate glaucoma patients with cataracts, the perimetry indices of SWAP testing improved after phacoemulsification and yellow-tinted IOL implantation. This suggests that the yellow-tinted IOLs have less effect on SWAP testing than visually significant cataracts
