Maximum variation was seen with HOA and minimum with LOA. In eyes with OSI ≥1, the repeatability with Pentacam AXL wave dropped with ICC ranging from 0.77 for HOA, to 0.84 for LOA with lower Sw, TRT, and COV of all aberration measurements as compared to iTrace. The Sw, TRT, and COV of all aberration measurements were significantly lower (better) than those of iTrace. All measurements with Pentacam AXL wave with OSI < 1 had excellent repeatability, intraclass correlation coefficient (ICC) ranging from 0.88 for HOA, to 0.92 for LOA.

OSI showed an inverse association with TBUT (P < 0.001).

Repeatability of Pentacam AXL wave and iTrace in healthy and postrefractive eyes (OSI >1 vs OSI <1) was studied using within-subject standard deviation (Sw) test-retest repeatability (TRT), coefficient of variation (COV). They underwent optical quality analyzer (OQAS, Visio metrics S.L, Terrassa, Spain) to assess objective scatter index (OSI), three scans each on Pentacam AXL wave (OCULUS Optikgerate Gmbh, Wetzlar, Germany), iTrace (Tracey™ Technologies, Texas, USA) for flat, steep keratometry, thinnest corneal thickness, root mean square higher-order aberrations (RMS HOA), RMS lower-order aberrations (LOA), spherical aberrations, RMS COMA. One hundred healthy and 100 postrefractive surgery eyes underwent dry eye evaluation including Schirmer's test and tear film break-up time (TBUT). To assess impact of tear optics on repeatability of a Scheimpflug device with a Hartmann Shack aberrometer and a ray tracing aberrometer. When opposed to the Melles approach, the big bubble technique generates a smooth interface with less stromal residue, which results in higher visual quality and contrast sensitivity. Results of point spread function (PSF) in big bubble group had superiority to Melles group with considerable statistical P value of 0.023. Contrast sensitivity reported as modulation transfer function (MTF) showed higher values in big bubble group and differences with Melles group weresignificant. Comparing the endothelial cell profile, corneal aberrations, corneal biomechanical properties and keratometry had no significantdifferences. Mean of sphere and cylinder refraction showed no significant difference between two groups. Mean BCSVA in big bubble group (0.18 ± 0.12 Log MAR) was significantly better than Melles group (0.35 ± 0.16 Log MAR). Mean UCVA in big bubble group was 0.61 ± 25 LogMAR and in Melles group was 0.89 ± 0.41 LogMAR (p-value 0.043). Uncorrected visual acuity (UCVA), best corrected spectacle visual acuity (BCSVA), manifest refraction, keratometric characteristics, contrast sensitivity, corneal aberrations, corneal biomechanical characteristics, and endothelial cell profile are the outcome measurements. Thirty-seven eyes were treated using the big bubble DALK method, while 35 eyes were treated using the Melles approach. Melles) in patients with advanced keratoconus. This study designed to compare the results of two different DALK surgery techniques (big bubble vs. This study conducted on 72 eyes of 72 participants. Melles) in patients with advanced keratoconus.Ī retrospective comparative clinical study. Without the support of these ladies and many others this recognition would have never been possible.Comparing results of two different DALK surgery techniques (big bubble vs. MaryBeth Smith for leading a great group of women to great success. You’ve taken me under your wing from one opportunity to the next and I’m so grateful for the doors you’ve opened for me. Kristen Arendale for guidance through the best days and the worst days… and the days still to come ☺️ You can’t get rid of me! Kim Vittorio for putting so much value in my abilities. She left parts of her heart with so many and I’ll never be able to put in words my gratitude for all the things she taught me and so many others. Linda Fuggiti for treating every single person she met as if they were family.

Patricia Wilson for being a wonderful mentor even when I flew the coop 😂 I appreciate all you did to support my growth. I’ll never be able to thank you enough for giving me the chance. Kelly Tompkins for being the FIRST person to see potential in me and for taking my career to the next level. But more than that, I’m beyond thankful for the women in my life who’ve led me to do great things. Today, on international women’s day, I’m thankful again for the opportunity to be recognized in my community with so many other great women.
