SICS-105: Phase recognition in Manual Small-Incision Cataract Surgery
<p><span>This prospective cross-sectional study introduces the first Manual Small-Incision Cataract Surgery (SICS) video dataset, which is prevalent but understudied in low- and middle-income countries (LMICs), evaluates effectiveness of phase recognition through deep learning (DL) using the MS-TCN++ architecture and compares its results with the well-studied phacoemulsification procedure using the Cataract-101 public dataset. Our novel SICS-105 dataset involved 105 patients recruited at Sankara Eye Hospital in India. Performance is evaluated with frame-wise accuracy, edit distance, F1-score, Precision-Recall AUC, sensitivity, and specificity. The MS-TCN++ architecture performs better on the Cataract-101 dataset across reported metrics, with an accuracy of 89.97% [CI 86.69-93.46%] compared to 84.94% [CI 79.45-92.03%] on the SICS-105 dataset (ROC AUC 99.10% [98.34-99.51%] vs. 98.22% [97.17-99.39%]). Reducing the 20 phases to 13 phase in SICS improved performance without completely bridging the gap. The per-video accuracy distribution and confidence-intervals overlap between the samples. PR-AUC curves for each phase in the SICS dataset range from 46.20 to 94.18%. In conclusion, we replicated phase recognition results from phacoemulsification in a new open-access SICS dataset using DL with slightly lower prediction performance. This research marks a crucial step towards improving postoperative analysis and training for SICS.</span></p>
Gender and age-related differences of ccular biometric parameters in patients undergoing cataract surgery in Bosnia and Herzegovina
<p><strong>Purpose</strong>: To determine the distribution and mutual relationship of ocular biometric parameters, as well as to evaluate gender- and age-related differences in patients undergoing cataract surgery in Bosnia and Herzegovina.</p> <p><strong>Materials and methods</strong>: It was a retrospective cross-sectional study of consecutive patients who underwent cataract surgery between January 2017 and December 2021 in a tertiary care clinic. All biometric measurements were performed using the optical biometer OA-2000 (Tomey, Nagoya, Japan).</p> <p><strong>Results</strong>: The study evaluated 1278 eyes from 1278 consecutive cataract patients. The average age of all included patients was 69.4 ± 9.98 (range 40–96). A total of 672 eyes (52.58%) were from females. The mean axial length (AL), anterior chamber depth (ACD), lens thickness (LT), and mean keratometry were 23.46±1.18mm, 3.17±0.40mm, 4.54±0.48mm, 43.42±1.55D respectively. Corneal astigmatism of ≥1D, >2D and >3D was found in 33.4%, 7.8% and 2.5% patients, respectively. Females were found to have shorter AL (p<0.0001), shallower ACD (p<0.0001) and steeper corneas (p<0.0001). In both genders, AL, ACD and with-the-rule astigmatism showed a decreasing trend (p=0.0001), while keratometry, the average cylinder, and against-the-rule astigmatism showed an increasing trend (p=0.0001) with increasing age. Furthermore, in both genders, there was an increasing trend in ACD (p=0.0001), and a decreasing trend in keratometry (p=0.0001) and LT (p=0.0001) with increasing AL.</p> <p><strong>Conclusions</strong>: This study provides useful reference data on ocular biometry for cataract surgeons in Bosnia and Herzegovina. Female patients tend to have steeper corneas, shorter AL and shallower AC than males, and these differences are independent of age or AL.</p>
Video Dataset of 101 Cataract Surgeries
<p>This dataset contains 101 videos of cataract surgeries annotated with two kinds of information:</p> <ul> <li>(Anonymous) ID and experience level of operating surgeon</li> <li>Starting points of quasi-standardized operation phases in videos</li> </ul> <p>The cataract surgeries have been performed by four different surgeons of two levels of experience (low, high).</p> <p>The dataset has been collected and annotated by ophthalmic surgeons of<br> Klinikum Klagenfurt, and has been prepared and provided by the Institute of<br> Information Technology (ITEC) of Alpen-Adria-Universitaet (AAU) Klagenfurt, Austria.</p>
