Background: In contrast to photorefractive keratectomy (PRK), the corneal epithelium and Bowman's layer are preserved in LASIK. Thus, there should be less scarring and regression after LASIK than after PRK.
Patients: Between December 1993 and October 1995, we treated 113 eyes (66 patients). The Automated Corneal Shaper and the Keracor 116 excimer laser were used. We evaluated refraction, visual acuity and corneal topography.
Results: To date, 61 eyes reached six months follow up. Mean preoperative refraction was -14.3 D (-3.3 to -29 D; SD = 7). Mean deviation from target refraction was -1.4 D (-9.5 to +2.5 D; SD = 2.7) at six months. 34% were within +/-0.5 D of target refraction, 46% within +/-1 D, 67% within +/-2 D, and 82% within +/-3 D. Mean change of refraction ("regression") from one to six months postoperatively was +0.13 D (-7.5 to +8 D; SD = 2.1). Refractive change was < 0.5 D in 51%, < 1 D in 66%, < 2 D in 84%, and < 3 D in 89%. In 88% of eyes, the corneal interface was not or just barely visible, while it was clearly visible in 12%. No scars were observed.
Conclusions: Our results indicate that LASIK is an effective procedure in the correction of high myopia. The incidence of scar formation and regression is considerably lower than after PRK.

All-Metal Metamaterial-Based Sensor with Novel Geometry and Enhanced Sensing Capability at Terahertz Frequency.
Sensors (Basel)
January 2025
Department of Information Engineering, Electronics and Telecommunications (DIET), "La Sapienza" University of Rome, 00184 Rome, Italy.
This research proposes an all-metal metamaterial-based absorber with a novel geometry capable of refractive index sensing in the terahertz (THz) range. The structure consists of four concentric diamond-shaped gold resonators on the top of a gold metal plate; the resonators increase in height by 2 µm moving from the outer to the inner resonators, making the design distinctive. This novel configuration has played a very significant role in achieving multiple ultra-narrow resonant absorption peaks that produce very high sensitivity when employed as a refractive index sensor.
