Purpose
To compare higher order aberrations (HOA) and modulation transfer function (MTF) in eyes implanted with asymmetric refractive EDOF and trifocal IOLs.
Setting
Tertiary private eye hospital, India
Methods
A retrospective study where subjects implanted with asymmetric refractive EDOF (Lentis Comfort, Teleon Surgical BV) and Trifocal IOL (PanOptix, 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 in the study. 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 were obtained using i-Trace aberrometer for 4mm fixed pupil and compared among different groups.
Results
44 and 34 eyes were implanted with asymmetric refractive EDOF and trifocal IOL respectively. The Mean±SD age of the subjects implanted with asymmetric refractive EDOF and trifocal IOL were 58.80±10.1 and 57.88±8.55 year respectively (Two sample, p=0.66). Higher order aberrations were found to be similar in both the IOLs (two sample t test, p>0.05). MTF at all spatial frequencies were also similar in both the IOLs (Two sample t test, p>0.05).
Conclusions
We noted similar internal HOA and MTF in eyes implanted with asymmetric refractive EDOF and trifocal IOL.
