PURPOSE: To investigate re-innervation in the implanted lenticule, as well as changes to the cornea, after correcting hyperopia with an autologous implantation of a lenticule obtained through small incision lenticule extraction (SMILE). METHODS: This study retrospectively analysed re-innervation in the implanted lenticule, as well as microscopic morphological changes in the corneal architecture of the recipient cornea in five patients (with myopia in one eye and hyperopia in the contralateral eye) who received SMILE in the myopic eye and femtosecond laser in situ keratomileusis (FS-LASIK) combined with lenticule implantation in the contralateral hyperopic eye...

A 27-year-old woman had microkeratome-assisted laser in situ keratomileusis (LASIK) for moderate bilateral hyperopia. The preoperative ophthalmologic examination was unremarkable except for minimal lissamine green staining bilaterally on the nasal conjunctiva. On the first postoperative day, the uncorrected distance visual acuity (UDVA) was 20/20 bilaterally and the corneas were clear. Four days later, the patient presented with mild blur in both eyes. Examination showed diffuse bilateral epithelial cysts encompassing the central 6...

Background: Localized macular edema and retinal nerve fiber layer (RNFL) thinning have been reported shortly after laser in situ keratomileusis (LASIK) in adults. However, it is still unclear how LASIK affects the retina of children. This study aimed to investigate the macular retina and RNFL thickness in children with refractive amblyopia who underwent femtosecond laser-assisted LASIK (FS-LASIK). Methods: In this study, we included 56 eyes of 32 patients with refractive amblyopia who underwent FS-LASIK in our hospital from January 2012 to December 2016...

PURPOSE: To compare the astigmatism induced surgically (SIA) by spherical hyperopic laser in situ keratomileusis (H-LASIK) versus myopic laser in situ keratomileusis (M-LASIK) in nonastigmatic eyes. METHODS: A retrospective study of patients who underwent LASIK surgery between 2005 and 2014 at the Care-Vision Laser Center, Israel. We calculated the mean absolute SIA and performed risk factor analysis for induced astigmatism. Differences between H-LASIK and M-LASIK were analyzed...

REVIEW
T Kohnen, G Steinwender
OBJECTIVE AND PRINCIPLES: In LASIK, after cutting a lamellating stromal corneal incision (flap) with a microkeratome or a femtosecond laser, the underlying tissue is treated with an excimer laser for refractive correction. The objective is to achieve independency from spectacles and contact lenses due to correction of ametropia. INDICATIONS: Surgery is indicated when the patient wishes to achieve independency from spectacles and contact lenses. For LASIK, the German Commission for Refractive Surgery defined a range of applicability for myopic correction up to -8 diopters (D), astigmatic correction up to 5 D and hyperopic correction up to +3 D...
