Purpose
To compare higher order aberrations (HOA) and modulation transfer function (MTF) in eyes implanted with Trifocal and extended depth of focus (EDOF) IOLs.
Setting
Private Eye Hospital, India
Methods
A prospective study where subjects implanted with Trifocal IOLs (Acrysof IQ PanOptix, Alcon; Acrysof IQ VIVITY, Alcon) aged between 40 -75 years, post-operative best corrected visual acuity 0.2logMAR or better, pre operative corneal astigmatism <1.50D and cataract grade NS I-III were included. Subjects with any ocular pathologies, irregular astigmatism, previous refractive surgery, and intra-operative complications were excluded. At 1 month follow up, internal HOA (3rd, 4th and 5th order) and MTF at 5,10,15,20,25,30 cycle per degrees (CPD) were obtained using HOYA i-Trace aberrometer for 4mm fixed pupil and compared between two groups.
Results
87 and 18 eyes were implanted with PanOptix, and VIVITY respectively. The Mean±SD age of the subjects implanted with PanOptix and VIVITY IOL were 58.22±7.9 and 55.4±11.97 years respectively (P=0.46). Higher order aberrations were similar in both IOLs (p>0.05). MTF was found to be higher with PanOptix IOL at all spatial frequencies and the difference was significant at spatial frequencies of 15 (p=0.025), 20 (p=0.042), 25 (p=0.017) CPD.
