BACKGROUND AND PURPOSE: The KAMRA™ inlay (AcuFocus, Irvine, California, USA) is an additional option for correcting presbyopia that has been used for many years in refractive surgery. Our objective is to report our three-month postoperative results of KAMRA™ inlay implantation in terms of near, intermediate and distance vision. PATIENTS AND METHODS: All 24 patients (average age 54.1 ± 6.0 years) were treated with the KAMRA™ inlay in the non-dominant eye (75 % in the left eye) by the same surgeon (MEH)...

PURPOSE: To investigate refractive outcomes and induction of corneal higher order aberrations (HOA) in eyes that underwent laser-assisted in situ keratomileusis (LASIK) for high hyperopia correction using an aberration neutral profile with corneal vertex centration and asymmetric offset. METHODS: A total of 24 consecutive patients (38 eyes) who underwent LASIK by one surgeon using AMARIS 750S excimer laser and a Carriazo-Pendular microkeratome for flap creation were retrospectively analyzed...

Refractive surgical treatment of hyperopia still remains a challenge for refractive surgeons. A new nomogram of small incision lenticule extraction (SMILE) procedure has recently been developed for the treatment of hyperopia. In the present study, we aimed to evaluate the wound healing and inflammatory responses of this new nomogram (hyperopic-SMILE), and compared them to those of hyperopic-laser-assisted in situ keratomileusis (LASIK), using a rabbit model. A total of 26 rabbits were used, and slit lamp biomicroscopy, autorefractor/keratometer, intraocular pressure measurement, anterior segment optical coherence tomography, corneal topography, and in vivo confocal microscopy examinations were performed during the study period of 4 weeks...

PURPOSE: Case series report of normal-appearing eyes after hyperopic LASIK exhibiting diurnal shift in refractive error found to correlate with diurnal shifts in epithelial thickness profile. METHODS: Patients complaining of diurnal shift in vision during the course of the day with more hyperopia on waking and decreasing hyperopia in the evening in the absence of abnormal epithelial or slit-lamp findings were examined. Diurnal concomitant measurement of refraction, topography, and Artemis very high-frequency digital ultrasound scanning (VHFDU) (ArcScan Inc...

PURPOSE: To compare changes in the corneal thickness profile before and 6 months after femtosecond laser in situ keratomileusis (LASIK) for hyperopia. METHODS: In a prospective noncomparative case series study, 24 eyes of 20 hyperopic patients undergoing femtosecond LASIK were examined preoperatively and 6 months postoperatively. Corneal profile was measured using Pentacam HR device. Paired t test was used to compare preoperative and postoperative values. Spearman correlation analysis was performed to evaluate the relationship between the central corneal thickness changes and attempted spherical equivalent refraction (SER)...

PATIENTS AND METHODS: This retrospective cross-sectional study included 97 hyperopic eyes; 55 were treated with LASIK and 42 with PRK.

BACKGROUND: Previous studies have suggested that, to improve refractive predictability in hyperopic LASIK treatments, preoperative cycloplegic or manifest refraction, or a combination of both, could be used in the laser nomogram. We set out to investigate (1) the prevalence of a high difference between manifest and cycloplegic spherical equivalent in hyperopic eyes preoperatively, and (2) the related predictability of postoperative keratometry. METHODS: Retrospective cross-sectional data analysis of consecutive treated 186 eyes from 186 consecutive hyperopic patients (mean age 42 [±12] years) were analyzed...

PURPOSE: To evaluate corneal higher order aberrations after LASIK for the correction of high hyperopia using a 500-Hz excimer laser and optimized ablation profile. METHODS: Retrospective consecutive study including 51 eyes of 28 patients (age range: 21 to 54 years) with high hyperopia or hyperopic astigmatism (sphere ≥ 5.00 diopters). All cases underwent LASIK using the sixth generation Amaris excimer laser (SCHWIND eye-tech-solutions, Kleinostheim, Germany) and a femtosecond laser platform for flap creation...

PURPOSE: To compare differences in induced aberrations and visual acuity after wavefront-optimized LASIK and aspheric-customized LASIK for the treatment of hyperopia. METHODS: Forty consecutive eyes underwent uneventful LASIK for treatment of moderate hyperopia (+3.82 ± 0.63 diopters [D] [+2.75; +5.125]). A standard procedure was performed in the wavefront-optimized LASIK group (n = 24), whereas a postoperative Q-factor equal to zero was scheduled in the aspheric-customized LASIK group (n = 16)...

One week after LASIK, our patient presented with bilateral haloes and reduced vision. Examination revealed the typical central toxic keratopathy triad: corneal thinning, hyperopic shift and a reduction in best corrected visual acuity to 6/12, which, after commencing high-dose topical steroids, improved 6 months later to 6/6.

This review summarizes the current status of the small incision lenticule extraction (SMILE) procedure. Following the early work by Sekundo et al. and Shah et al., SMILE has become increasingly popular. The accuracy of the creation of the lenticule with the VisuMax femtosecond laser (Carl Zeiss Meditec) has been verified using very high-frequency (VHF) digital ultrasound and optical coherence tomography (OCT). Visual and refractive outcomes have been shown to be similar to those achieved with laser in situ keratomileusis (LASIK), notably in a large population reported by Hjortdal, Vestergaard et al...

INTRODUCTION: Use of the One Use-Plus SBK (Sub-Bowman's Keratomileusis) automated microkeratome (Moria, Antony, France) has been shown to be safe, predictable and comfortable for the creation of thin corneal flaps with a smooth and regular stromal bed. PURPOSE: To evaluate the use of the Moria One Use-Plus SBK (Moria, Antony, France) automated microkeratome on corneas with 180°-keratometry under 40 diopters (D). METHODS: We retrospectively studied cases that underwent SBK whose 180°-keratometry was under 40 D...

The purpose of this study was to evaluate the correlation of important risk factors for LASIK retreatment and the retreatment rate. A retrospective cohort study was conducted. Records of patients who underwent LASIK between January 2011 and January 2012 at the Zambrano-Hellion Medical Center, Tec de Monterrey (México), and posteriorly underwent LASIK retreatment were identified and risk factors to receive retreatment were assessed using relative risk. Main outcomes were retreatment rate, risk factors for retreatment, and uncorrected distance visual acuity (UDVA)...
