The following is a summary of “Refractive outcomes of immediately sequential bilateral cataract surgery in eyes with long and short axial lengths,” published in the February 2024 issue of Ophthalmology by Pollmann et al.
Researchers conducted a retrospective study to present the refractive results observed in eyes with long (≥25.00 mm) and short (≤22.00 mm) axial lengths (AL) following immediately sequential bilateral cataract surgery (ISBCS).
They conducted a study in which patients who underwent ISBCS were selected. The eyes of patients with both bilateral long and short ALs were included in the analysis. Pre- and postoperative biometric measurements, autorefraction data, and ocular comorbidities or complications were documented. The primary focus was on determining the mean refractive prediction error.
The results showed that out of the 37 patients (74 eyes) with long ALs and 18 patients (36 eyes) with short ALs included in the study, the mean ± standard deviation of ALs were 26.40 ± 1.38 mm and 21.44 ± 0.46 mm in the long and short AL groups. Among eyes with long ALs, the mean absolute error from the biometry-predicted refraction was -0.16 ± 0.46 D, with 74% of eyes achieving a refraction within ±0.50 D of the predicted value. In eyes with short ALs, the mean absolute error was -0.63 ± 0.73 D, with only 44% of eyes achieving a refraction within ±0.50 D of the predicted value. Eight (44.4%) patients with short AL eyes exhibited a myopic deviation greater than ±0.50 D from the predicted result in both eyes.
Investigators concluded that patients with short AL eyes undergoing ISBCS had less predictable refractive outcomes, achieving the desired correction less frequently compared to those with long AL eyes.
