Purpose

The objective of this study was to compare the accuracy of theoretical calculations of intraocular lens power using ocular biometry with ORA VLynk intraoperative aberrometry after cataract surgery in short and long eyes. 

Setting

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 intraocular lens 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 for this study and the difference between predicted and postoperative spherical equivalent (numerical error), and proportion of eyes within ±0.50D and ±1.00D of their target spherical equivalent refraction were calculated. The power of the implanted AcrySof IQ SN60WF lens was determined by the ORA VLynk intraocular lens power calculation system. The standard preoperative measurements included refraction, visual acuity and ocular biometry. The predicted residual refractive error was calculated preoperatively 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 in all eyes. The postoperative spherical equivalent was compared with the predicted spherical equivalent to evaluate the accuracy the different formulas and the ORA VLynk intraocular lens power calculation system. 

Conclusion

Intraoperative aberrometry with ORA VLynk provides good refractive results in calculating intraocular lens power in short and long eyes.
