Studying morphological changes of cornea in the remote postoperative period is becoming increasingly relevant with refractive surgeries being adapted for children. PURPOSE: comparative analysis of keratocyte density and hystomorphologic changes of cornea after laser in situ keratomieleusis (LASIK) and femtosecond laser-assisted LASIK (FS-LASIK) in children with hyperopia. MATERIAL AND METHODS: 109 patients aged 6-17 years in 2 groups were examined with 'Confoscan-4' confocal microscope...

PURPOSE: To report three cases of late-onset (7-14 years postoperative) traumatic dislocation of laser in situ keratomileusis (LASIK) flaps with epithelial ingrowth that all had delayed surgical intervention. METHODS: A retrospective, interventional case series of three patients who underwent flap repositioning and mechanical debridement of epithelial ingrowth, all after an initial delayed diagnosis/treatment of dislocated LASIK flap. RESULTS: Visual improvement was noted in all three cases following LASIK flap repositioning and debridement of epithelial ingrowth; patient 1 improved from 20/800 corrected-distance-visual-acuity (CDVA) to 20/20 uncorrected-distance-visual-acuity (UDVA) postoperative (14 years post-LASIK, 5-week interval between injury and surgery), patient 2 improved from 20/50 CDVA to 20/20 CDVA (10 years post-LASIK, 4-month interval between injury and surgery) and patient 3 improved from 20/80 CDVA to 20/60 CDVA (7 years post-LASIK, 14-month interval between injury and surgery)...

PURPOSE: To describe a case in which post-LASIK corneal ectasia was treated using an allogeneic lenticule implanted into the recipient eye. METHODS: A 29-year-old man presented with bilateral ectasia 10 years after LASIK. Manifest refraction was -1.50 -3.25 × 15° in the right eye and -13.50 -6.00 × 10° in the left eye. Because of contact lens intolerance in the left eye, the authors decided to implant an allogenic corneal lenticule, created by small incision lenticule extraction with the VisuMax laser (Carl Zeiss Meditec, Jena, Germany) in a donor eye with a refraction of +5...

PURPOSE: To report the outcomes of enhancement after small incision lenticule extraction (SMILE) using the VisuMax CIRCLE option (Carl Zeiss Meditec AG, Jena, Germany), which converts the SMILE cap into a femtosecond LASIK flap for secondary excimer laser application. METHODS: Of 2,065 SMILE procedures, 22 eyes (1.1%) re-treated with CIRCLE with a follow-up of 3 months were included in the analysis. SMILE was performed in the usual manner. For re-treatment, the CIRCLE procedure was performed with pattern D flap creation on the VisuMax system and subsequent excimer laser ablation with a Zeiss MEL 90 laser (Carl Zeiss Meditec) with plano target in all cases...

REVIEW
Darren Shu Jeng Ting, Sathish Srinivasan, Jean-Pierre Danjoux
The number of laser in situ keratomileusis (LASIK) procedures is continuing to rise. Since its first application for correcting simple refractive errors over 25 years ago, the role of LASIK has extended to treat other conditions, including postkeratoplasty astigmatism/ametropia, postcataract surgery refractive error and presbyopia, among others. The long-term effectiveness, predictability and safety have been well established by many large studies. However, due to the creation of a potential interface between the flap and the underlying stroma, interface complications such as infectious keratitis, diffuse lamellar keratitis and epithelial ingrowth may occur...

BACKGROUND: To compare the incidence of rainbow glare (RG) after femtosecond laser assisted-LASIK (FS-LASIK) using the upgraded FS200 femtosecond laser with different flap cut parameter settings. METHODS: A consecutive series of 129 patients (255 eyes) who underwent FS-LASIK for correcting myopia and/or astigmatism using upgraded WaveLight FS200 femtosecond laser with the original settings was included in group A. Another consecutive series of 129 patients (255 eyes) who underwent FS-LASIK using upgraded WaveLight FS200 femtosecond laser with flap cut parameter settings changed (decreased pulse energy, spot and line separation) was included in group B...

Background: Since thin and high-quality flaps produce more satisfactory surgical outcomes, flaps created by mechanical microkeratomes are more economical as compared with femtosecond lasers, and no Iranian study has concentrated laser in situ keratomileusis (LASIK) flap peculiarities between Moria Sub-Bowman keratoplasty (SBK) microkeratomes and LDV femtoseconds, the present study compares and contrasts them. Materials and Methods: This cross-sectional study was done on all patients who underwent LASIK surgery 1-month before this study...

Purpose: Interface bonding with corneal crosslinking (CXL) after LASIK using two different photosensitizers was studied ex vivo. Methods: A LASIK flap was created in enucleated rabbit eyes using a femtosecond laser. After the dissection, CXL was performed to seal the interface. In one group interface CXL was performed using rose bengal and green light, whereas in a second group riboflavin and UV-A light was used. In both groups irradiance, radiant exposure, dye concentration, and imbibition time was varied...

PURPOSE: To determine the usefulness of a silicone-hydrogel bandage contact lens (BCL) in the immediate postoperative period after uneventful myopic laser in-situ keratomileusis (LASIK). METHODS: The study design was randomized but not masked and data collection was prospective. This study comprised 51 consecutive myopic eyes intervened by means of the LASIK technique to compensate their refractive error. Patients were randomly assigned to two different groups. The experimental group included 24 eyes of 12 patients that were fitted with a BCL immediately after the flap replacement...
