Abstract Details


To compare visual and refractive outcomes of IOL surgery performed with vs. without the co-implantation of a CTR.


Optegra Eye Hospitals, UK


A retrospective audit of visual and refractive outcomes of consecutive IOL surgeries performed by a single surgeon with vs. without CTR implantation recorded in an electronic medical records system was undertaken. Treatments from 1 July 2018 to 10 October 2019 were included. Monocular uncorrected distance visual acuity (UDVA) for multifocal IOLs and corrected distance visual acuity (CDVA) for monofocal IOLs were assessed along with refractive predictability (deviation from predicted postoperative refraction, PPOR) for both groups. Chi Square test was used to compare the relevant proportions between the CTR and non-CTR groups and sub-analysis compared these outcomes for different IOL types.


516 eyes were implanted with multifocal IOLs (303 with and 213 without CTR). 74.3% and 71.4% of eyes achieved UDVA of 20/20 or better, while 83.0% and 77.0% of eyes had a postoperative SEQ within ±0.50D of PPOR, in the with vs. without CTR groups respectively. 89 eyes were implanted with a monofocal IOL (28 with and 61 without CTR). 75.0% and 83.6% of eyes achieved CDVA of 20/20 or better and 64.3% vs. 71.2% were within ±0.50D of PPOR in the with vs. without CTR groups respectively. Differences between groups were not statistically significant (p>0.05).


Visual and refractive outcomes achieved were favourable for the entire cohort and no statistically significantly differences were observed with vs.without co-implantation of a CTR. Outcomes of different monofocal and multifocal lens models were also similar for the CTR vs. non-CTR groups.
