Purpose
To evaluate defocus curve in eyes implanted with asymmetric refractive and non diffractive extended depth of focus (EDOF) IOLs.
Setting
Tertiary private eye hospital, India
Methods
A retrospective study where subjects implanted with EDOF IOLs (Lentis Comfort, Teleon Surgical BV; Acrysof IQ VIVITY, Alcon), aged between 40 -75 years, BCVA 0.2logMAR or better was included. Subjects with ocular pathologies, any intraoperative complications were excluded. At 1month follow up, monocular distance corrected defocus curve measured in each subject using logMAR chart. The visual acuity with each defocus lens ranging from+2.00 to -3.0D (0.5D steps) was measured in randomized order.
Results
41 and 35 eyes were implanted with asymmetric refractive and non diffractive EDOF respectively. The Mean±SD age of the subjects implanted with Comfort Lentis and VIVITY IOL were 58.8±10.3 and 53.7±12.5 years respectively (P=0.17). Although Visual acuities with defocus upto -1.5 D were better with asymmetric refractive EDOF IOL it did not show statistical significance. Visual acuities beyond -1.5 D to -3.00 D defocus were better with non diffractive EDOF IOL and was significantly different at -3.0D (p=0.04).
Conclusions
Defocus curve showed that both IOL performed similar till intermediate distance whereas non diffractive IOL performed better at near as compared to asymmetric refractive IOL.
