AI Article Synopsis
- The study compares the visual and refractive results of two eye surgeries, SMILE and wavefront-guided LASIK, over a 2-year period in patients with myopia and myopic astigmatism.
- Both surgeries showed similar corrected distance visual acuity (CDVA), but SMILE had significantly better uncorrected distance visual acuity (UDVA) outcomes, with 100% of patients achieving closer results to their target refraction compared to 73% in the LASIK group.
- The findings suggest that SMILE provides superior long-term refractive outcomes compared to wavefront-guided LASIK, highlighting its effectiveness in treating myopia and myopic astigmatism.
Article Abstract
Purpose: To compare the 2-years visual and refractive outcomes between small-incision lenticule extraction (SMILE) and wavefront-guided laser in situ keratomileusis (LASIK) in eyes with myopia and myopic astigmatism.
Methods: Our retrospective case-control study examined 30 eyes of 30 patients with the manifest refraction spherical equivalent (MRSE) of -3.71 ± 1.83 dioptres (D) who underwent SMILE and 30 eyes of 30 patients with MRSE of -3.81 ± 1.40 D who underwent wavefront-guided LASIK. We assessed the 2-years clinical outcomes.
Results: Logarithm of the minimal angle of resolution (LogMAR)-corrected distance visual acuity (CDVA) was -0.23 ± 0.07 in the SMILE group and -0.24 ± 0.07 in the wavefront-guided LASIK group 2 years postoperatively (p = 0.82). Logarithm of the minimal angle of resolution-uncorrected distance visual acuity (UDVA) was -0.18 ± 0.09 and -0.15 ± 0.11 (p = 0.30, respectively). In the SMILE and wavefront-guided LASIK groups 2 years postoperatively, 100% and 73% of eyes, respectively, were within 0.5 D of the prompted MRSE correction (p = 0.005). Changes in the MRSE of -0.10 ± 0.30 D and -0.23 ± 0.51 D occurred from 3 months to 2 years (p = 0.40, respectively). We found a significant correlation between myopic regression and the changes in the keratometric readings from 3 months to 2 years after wavefront-guided LASIK (r = -0.48, p = 0.002), but not after SMILE (r = -0.004, p = 0.90).
Conclusion: Small-incision lenticule extraction offers better refractive outcomes than wavefront-guided LASIK during a 2-years follow-up for the correction of myopia and myopic astigmatism.

Impact of Scleral Lenses on Visual Acuity and Ocular Aberrations in Corneal Ectasia: A Comprehensive Review.
J Pers Med

Ophthalmology, Campus Bio-Medico University, 00128 Rome, Italy.
Corneal ectasias, including keratoconus (KC), pellucid marginal degeneration (PMD), and post-LASIK ectasia, poses significant visual rehabilitation challenges due to the resultant irregular astigmatism, myopia, and higher-order aberrations (HOAs). These conditions often resist traditional corrective methods, necessitating advanced optical solutions. Scleral lenses (SLs) have emerged as a primary non-surgical option for managing these complex corneal irregularities.

- This study aimed to compare the early visual quality, specifically low contrast acuity (LCVA), between two types of eye surgery: SMILE and LASIK.
- The analysis involved military personnel who underwent either SMILE or two types of LASIK (wavefront-guided and wavefront-optimized), evaluating their night vision and LCVA up to three months after surgery.
- Results showed that LASIK patients had better night vision and photopic LCVA at one month compared to SMILE patients, while WFO LASIK had mixed results at three months, indicating that LASIK might lead to faster recovery of visual quality than SMILE.

Purpose: To compare the visual quality after wavefront-guided femtosecond LASIK (WFG FS-LASIK) in patients with different levels of preoperative total ocular higher-order aberrations to guide clinical decision-making regarding patient selection and treatment strategies.
Methods: This study included 112 right eyes of 112 patients who previously underwent WFG FS-LASIK for correcting myopia and myopic astigmatism. The patients were divided into two groups based on the mean values of preoperative total ocular HOAs (0.
