In this prospective North American case series, investigators considered how consecutive phacoemulsification patients fared when treated by residents versus staff surgeons. Of the 8,738 cases included, 3,845 involved resident participation, with 82% of these performed entirely by the trainees themselves. The staff surgeons meanwhile completed 56% of cases without any trainee involvement. Approximately 1/3 of the cases were categorized as complex. When simple and complex cases were compared, investigators found that there was no difference in overall complication rates, posterior capsular rupture rates, or vitreous loss rates. Investigators concluded that in terms of complication rates both groups fared the same.

Surgical options for enhancement after SMILE: the advantages and disadvantages

Does the fact that the SMILE procedure lacks a standard enhancement approach hinder acceptance of the technique? Investigators pointed out that not only have more than 1 million patients undergone SMILE worldwide, but visual results were nearly equivalent to LASIK, which has had 20 years to improve outcomes. Still, inevitably some require retreatment. Investigators reviewed advantages and disadvantages of the retreatment options, which include surface ablation, thin-flap LASIK, CIRCLE, and re-SMILE, and also considered the literature to compare visual outcomes. Based on this, investigators provided retreatment decision-making guidance, offering an algorithmic approach.

Precision of intraocular lens power prediction in eyes shorter than 22 mm: an analysis of six formulas

Ankur Shrivastava, MS, Pranayee Behera, MS, Binod Kumar, BSc (Optometry), Siddhartha Nanda, MD
The aim of investigators in this retrospective study, involving eyes with an axial length of less than 22 mm, was to compare the precision of six different lens power formulas in such eyes. Included here were 50 eyes that met the axial length requirement. Investigators analyzed outcomes with each of the six formulas, the Barrett Universal II, Haigis, Hoffer Q, Holladay 2, Hill-RBF, and SRK/T, and compared the median absolute error. They found that there was no significant statistical difference with these with either post hoc analysis or Bonferroni correction for multiple comparisons. Investigators concluded that in eyes shorter than 22 mm, all six of the formulas offered equally accurate results for predicting intraocular lens power.
