Purpose: To determine the factors associated with retreatment after laser in situ keratomileusis (LASIK) for myopic eyes in the modern LASIK era.

Setting: Care-Vision Laser Centers, Tel-Aviv, Israel.

Design: Retrospective cohort study.

Methods: All cases of myopic LASIK performed between January 2005 and December 2012 were analyzed according to whether they had retreatment refractive surgery.

Result: The study evaluated 9177 right eyes in 9177 consecutive LASIK cases. The mean preoperative subjective spherical equivalent and astigmatism were -3.30 diopters (D) ± 1.53 (SD) (range -0.50 to -12.00 D) and 0.69 ± 0.94 D (range 0.00 to 6.00 D), respectively. Of the eyes, 165 (1.80%) had at least 1 retreatment. Over the course of the study, the 2-year retreatment rate decreased from 2.58% to 0.38% (P < .001). Multiple binary logistic regression analysis showed that older age (odds ratio [OR], 1.03; P = .007), higher astigmatism (OR, 1.23; P = .008), sphere (OR, 1.15; P = .026), and mean keratometric power (OR, 1.13; P = .036) significantly increased the odds for retreatment. A larger optical zone ablation (7.0 mm) significantly decreased the odds for retreatment (OR, 0.10; P = .022). Significant cutoffs associated with retreatments were age greater than 50 years, astigmatism more than 1.5 D, and sphere more than 2.0 D.

Conclusions: Older age and higher preoperative astigmatism, sphere, and corneal steepness were associated with myopic LASIK retreatment. Larger optical ablation zones might decrease retreatment rates.

Novel coumarin-triphenyliminophosphorane (TPIPP) fluorophores, synthesized via a nonhydrolytic Staudinger reaction, exhibit remarkable redox-responsive optical properties. Upon chemical and electrochemical oxidation, these compounds display a hypsochromic shift in absorption from 430 to 350 nm, accompanied by up to 11-fold fluorescence enhancement under 405 nm excitation. The fluorescence switching occurs at an electrochemical oxidation potential of approximately +2.

Early diagnosis of tumors allows effective treatment of primary cancers through localized therapeutic interventions. However, developing diagnostic tools for sensitive, simple, and early tumor (especially less than 2 mm in diameter) detection remains a challenge. Herein, we presented a biomarker-activatable nanoprobe that enabled a near-infrared (NIR) photothermally amplified signal for fluorescence imaging and urinalysis of tumor.

Deep eutectic solvents (DES) have emerged as versatile, sustainable media for the synthesis of nanomaterials due to their low toxicity, tunability, and biocompatibility. This study develops a one-step method to modify commercially available screen-printed electrodes (SPE) using laser-induced pyrolysis of DES, consisting of choline chloride and tartaric acid with dissolved nickel acetate and dispersed graphene. The electrodes were patterned using a 532 nm continuous-wave laser for the in situ formation of Ni nanoparticles decorated on graphene sheets directly on the SPE surface (Ni-G/SPE).
