Evaluation of retinal light scattering, visual acuity, refraction and subjective satisfaction in patients after acrysof iq panoptix intraocular lens implantation
Abstract
Aim: To evaluate the retinal light scattering, visual acuity, refraction and subjective satisfaction in patients after implantation of Acrysof IQ PanOptix intraocular lens. Methods: Our group included 32 eyes of 21 patients who underwent cataract surgery or refractive lensectomy with Acrysof IQ PanOptix multifocal intraocular lens implantation at the Ophthalmology Clinic of Faculty Hospital Hradec Králové during the time from September 2015 to December 2017.
The observed parameters were visual acuity, subjective refraction, retinal light scattering and patient' subjective satisfaction. Preoperative refractive values and visual acuity values were compared with results obtained on day 1, 1 month and at an average of 27 months postoperatively.
Subjective satisfaction and degree of light scattering on the retina were evaluated at the end of the follow-up period. Results: Preoperative, uncorrected distant visual acuity improved from an average of 0,51 +- 0,29 (expressed in decimal values) to 0,94 +- 0,10 at the end of the follow-up period.
Preoperative best-corrected distance visual acuity improved from an average of 0,95 +- 0,19 to 1,00 +- 0,09 at the end of the followup period. The mean value of preoperative uncorrected near visual acuity was 8,29 +- 4,93 of Jaeger charts, the mean value of uncorrected near visual acuity at the end of the follow-up period was 1,00 +- 0 of Jaeger charts.
Subjective satisfaction was assessed using a standardized VF-14 questionnaire at least 1 year after surgery (mean follow-up of 27 months). Retinal light scattering was examined using an Oculus C-Quant instrument.
The retinal light scattering value in our sample was 1,12 +- 0,19. In only 6 eyes of 4 patients, the resulting value was outside the physiological range used for eyes with lens crystallina Conclusion: The value of light scattering on the retina is a factor affecting the degree of sensitivity to glare after implantation of multifocal intraocular lenses.
In our group, we observed a deviation from the physiological range of retinal light scattering in only 6 eyes of 4 patients, but this did not lead to a deterioration in subjective postoperative satisfaction.
