PURPOSE: We investigated the effect of enhanced monofocal intraocular lenses (IOL) (TECNIS Eyhance DIB00V) on retinal sensitivity in glaucoma patients after cataract surgery by comparing results with of such patients implanted with non-enhanced monofocal intraocular lenses (TECNIS ZCB00V). PATIENTS AND METHODS: This was a multi-facility retrospective study of glaucoma patients who had undergone cataract surgery. We measured the value of the foveal threshold with a Humphrey visual field analyzer before and after cataract surgery and considered this value to represent the sensitivity of the retina. As a sub-analysis, we also compared the mean deviation (MD), pattern standard deviation (PSD), thickness of ganglion cell complex (GCC), and best corrected visual acuity (BCVA) before and after surgery. We used t-tests to determine statistical differences between lens groups. RESULTS: We included 60 glaucoma patients (104 eyes) who underwent cataract surgery: enhanced group, n = 58 eyes; non-enhanced group, n = 46 eyes. In both groups, cataract surgery improved the retinal sensitivity (p < 0.001), MD (p < 0.001) and BCVA (p < 0.001). The postoperative foveal thresholds did not significantly differ by lens type (p = 0.673), at 34.41 ± 2.44 dB in the enhanced group and 34.61 ± 2.19 dB in the non-enhanced group. Likewise, there was no significant difference (p = 0.942) among advanced glaucoma patients, with postoperative foveal thresholds of 33.08 ± 2.35 dB and 33.17 ± 3.45 dB in the enhanced and non-enhanced, respectively. CONCLUSIONS: Implantation of enhanced monofocal IOLs in glaucoma patients did not result in any apparent loss of sensitivity compared with non-enhanced monofocal lens implantation.
