In the journal: May 2020 Intraocular lens power calculation in eyes with keratoconus: a review Nuria Garzón, PhD, Pedro Arriola-Villalobos, MD, Gema Felipe, Msc, Francisco Poyales, MD, María García-Montero, PhD This literature review documented the published methods being used to calcu- late IOL power for patients with keratoconus, looking specifically at papers that focused on related parameters and formulas. The review found that there are few publications that detail IOL power calculations for this population. Those that did found the SRK/T formula to have the best outcomes. According to the research, hyperopia was more likely to occur if the keratometric value used was based on the standard refractive index. Researchers also found the more severe the keratoconus, the greater the deviation from refractive target postop. Comparison of visual and refractive outcomes of two trifocal intraocular lenses Filomena Ribeiro, MD, Tiago Ferreira, MD Sixty patients were included in this double-arm, randomized, prospective case series, receiving either bilateral implantation of the FineVision Toric Pod FT IOL (PhysI- OL) (n=30) or the AcrySof IQ PanOptix Toric IOL (Alcon) (n=30). Patients were evaluated at 3 months postop on several parameters, including visual and refractive outcomes, contrast sensitivity, IOL alignment, and quality of vision. There was no difference in uncorrected or corrected distance or near visual acuities, though the PanOptix resulted in better intermediate vision around 60 cm. There were also similar levels of contrast sensitivity, quality of vision, and spectacle independence in the two groups. Mean IOL axis misalignment was 1.59 ± 2.15° and 1.89 ± 3.31° for PanOptix and Pod FT, respectively. Mean magnitude of error for astigmatic correc- tion was –0.09 D and –0.11 D for PanOptix and Pod FT, respectively. Sutureless scleral fixation using Carlevale lens: surgical and refractive outcomes Francesco Barca, MD, Tomaso Caporossi, MD, Lorenzo de Angelis, MD, Fabrizio Giansanti, MD, Alfonso Savastano, MD, Laura Di Leo, MD, Stanislao Rizzo, MD Researchers evaluated the Carlevale IOL (Soleko) as an option for a sutureless scleral fixation technique in 32 eyes of patients who were aphakic (n=9), had a dis- located IOL (n=22), or a subluxated crystalline lens (n=3). The mean preoperative BCVA was 0.46 ± 0.29; BCVA at 8 months of follow-up was 0.13 ± 0.12 logMAR (p<0.05). IOL tilt was 2.08 ± 1.19°. In terms of complications, one patient expe- rienced transient CME, another had vitreous hemorrhage, and two had pigment dispersion/reverse pupillary block. Lens dislocation, conjunctival erosion, and plug externalization did not occur in the follow-up period. With these results, the researchers concluded that the Carlevale IOL is a valid option for sutureless scleral fixation.

In memoriam as it is possible that current full time attend- ings were previously in private practice and vice versa. We therefore think it will be bene- ficial to evaluate years of teaching experience in order to answer this question. It would additionally have been beneficial to include surgical case volume with the residents for each attending, as this is not necessarily re- flected in full time vs. voluntary faculty status. Specifically, a multi-institution retrospective comparison of resident intraoperative and postoperative outcomes based on attending teaching experience and surgical case volume with residents is needed to more definitively answer the question of whether teaching ex- perience has an effect on complication rates. Moreover, ultimate surgical outcomes for pa- tients, such as vision and IOP after surgery, 11 should be included in any future studies to determine true outcomes after surgery.
