PURPOSE: To evaluate the feasibility of contrast sensitivity (CS) testing using a head-mounted binocular perimeter (IMO vifa) and to describe postoperative CS in eyes implanted with three types of intraocular lenses (IOLs).
PATIENTS AND METHODS: This retrospective single-center study included 102 eyes of 71 patients who underwent uncomplicated cataract surgery with implantation of a segmented refractive IOL (Lentis Comfort [LC], 38 eyes), an enhanced monofocal IOL (Tecnis Eyhance DIB00V [DIB], 33 eyes), or a standard monofocal IOL (Tecnis DCB00V [DCB], 31 eyes). CS was measured in each eye with both eyes open under photopic room lighting 1 month postoperatively, and the area under the log CS function (AULCSF) was calculated. Groups were compared using age-adjusted linear regression accounting for inter-eye correlation.
RESULTS: Testing required approximately 5 min per patient. Mean AULCSF was 1.35 ± 0.27, 1.19 ± 0.26, and 1.30 ± 0.24 in the LC, DIB, and DCB groups, respectively. No statistically significant difference was detected among the groups after age adjustment (p = 0.304). Compared with DCB, the adjusted differences were 0.017 (95% CI -0.113 to 0.148) for LC and -0.082 (95% CI -0.213 to 0.049) for DIB.
CONCLUSION: CS testing with the IMO vifa was feasible at routine postoperative visits under ambient room lighting. Further prospective studies are needed to assess its repeatability and agreement with established CS tests.
