Purpose
To analyze the effect of corneal spherical aberrations on the choice of extended range intraocular lenses to optimize the visual quality of patients.
Setting
Hospital Universitario Sanitas, La Moraleja.
Methods
The sample consisted of 33 patients, bilaterally implanted with one of the following intraocular lens (IOL) models: 22 eyes, AcrySof® IQ Vivity™ (Alcon Laboratories, Inc, Fort Worth TX), 22 eyes LuxSmart™ (Bausch & lomb GmbH, Berlin, Germany) and 22 eyes Vivinex™ (Hoya Surgical Optics, Tokyo, Japan). Corneal spherical aberration analysis was performed with Pentacam HR® (Oculus Optikgeräte GmbH, Germany).
One month after surgery, uncorrected distance and near visual acuity was assessed under photopic conditions using the ETDRS test. A statistical significance criterion P< 0.05 was considered and sample correlation was performed with Spearman's test.
Results
Preoperative spherical aberration (Z40) values measured at 6mm were Vivity™️ 0.324±0.07(μm), LuxSmart™️ 0.360±0.117(μm), and Vivinex™️ 0.313±0.09(μm). The mean pupillary diameter of the sample was 2.60±0.33mm, with a maximum value of 3.35mm and a minimum value of 2.04mm. All patients experienced an improvement in postoperative uncorrected distance visual acuity (UDVA) with values of (-0.05±0.06 LogMar) for Vivity™️, (-0.01±0.03 LogMar) for LuxSmart™️, and (-0.00±0.05 LogMar) for Vivinex™️. When correlating the parameters Z40 and UDVA in all models, no significance was observed, the same occurred when correlating UIVA and Z40. However, for the lens Vivinex™️ a correlation between z40 and UNVA was observed (p-value -0.499).
Conclusions
All three intraocular lens models studied provide optimal distance and near visual acuity, although the Vivinex™️ lens performed best in near vision. The Vivity™️ and LuxSmart™️ lenses have shown that extreme values of corneal spherical aberrations (Z40) do not affect the patient's distance vision. However, for the Vivinex™️ lens, this parameter must be considered to prevent worsening in near vision.
