Oftalvist, Spain
Methods
This prospective consecutive case series study was approved by the Ethics Committee de la Investigación con Medicamentos (Cádiz, Spain) and was conducted in accordance with the tenets of the Declaration of Helsinki. The study was registered at the DRKS German Clinical Trials Register (clinical registration number DRKS00028106). Eyes with short axial length, less than 22.1 mm, or long, greater than 25 mm, with implantation of the monofocal IOL implantation AcrySof IQ SN60WF were included. The exclusion criteria considered were corneal opacity, previous corneal surgery, vitrectomy, diabetic retinopathy, keratoconus, amblyopia and/or strabismus.
Results
50 eyes were considered and the difference between predicted and postoperative spherical equivalent, and proportion of eyes within ±0.50D and ±1.00D of their target spherical equivalent refraction were calculated. The power of the implanted lens was determined by the ORA VLynk. The predicted residual refractive error was calculated using the Hoffer Q, Holladay 2, Haigis, SRK/T, Barrett Universal II, and Barrett True-K formulas, as well as intraoperatively with the ORA VLynk system. Postoperatively, refractive error and visual acuity was measured. The postoperative spherical equivalent was compared with the predicted spherical equivalent to evaluate the accuracy the different formulas and the ORA VLynk IOL power calculation system.
