Purpose: To evaluate postoperative visual performance and total ocular aberration in cataract patients after implantation of the TECNIS Eyhance™ intraocular lens (IOL).
Methods: Our study is a prospective interventional non-comparative study that was conducted on 34 eyes of 17 patients who underwent phacoemulsification and Eyhance IOL implantation. Postoperative corrected and uncorrected near and far visual acuity and total ocular aberration were assessed 3 months after surgery.
Results: Our study included 34 eyes of 17 patients. At the third postoperative month, the mean spherical equivalent (SE) was -0.32 diopters (D) (SD ±0.62), and the mean distance-corrected near visual acuity (DCNVA) was 0.33 (SD ±0.15) and 0.42 (SD ±0.17) decimal notation (DN) monocular and binocular, respectively. The mean near distance with maximum visual acuity was 79.47 cm (SD ±7.70) and 74.76 cm (SD ±7.90) monocular and binocular, respectively. The mean postoperative minimum reading addition (add) was 1.6 D (SD ±0.47). The mean spherical aberration (SA) was 0.13 µm (SD ±0.09). The correlation of amount of spherical aberration with power of minimum reading add at 40 cm was not statistically significant (p=0.324).
Conclusion: The TECNIS Eyhance IOL provides good intermediate visual acuity and decreases the power of the reading add needed after phacoemulsification.
