Purpose: To evaluate the clinical outcomes of laser in situ keratomileusis (LASIK) using a new approach for the calculation of the ablation profile based on wavefront vertexing from pupil plane to corneal.
Methods: One hundred eyes of 50 patients (age, 21-41 years) with low and moderate myopia were enrolled in this prospective case series. All of them underwent topography-integrated wavefront-guided (TI-WFG) LASIK using the STAR S4IR excimer laser platform (Johnson & Johnson Vision).
Purpose: To analyze the outcomes of intracorneal ring segment (ICRS) implantation for the treatment of keratoconus based on preoperative visual impairment.
Design: Multicenter, retrospective, nonrandomized study.
Methods: A total of 611 eyes of 361 keratoconic patients were evaluated.
Purpose: To evaluate and characterize the clinical features of corneal ectasia after myopic laser in situ keratomileusis (LASIK) considering internal astigmatism and corneal aberrations and their correlation with other clinical data.
Setting: Vissum-Instituto de Oftalmológico de Alicante, Alicante, Spain.
Design: Retrospective comparative case series.
Purpose: To evaluate the clinical features of keratoconus taking into consideration anterior corneal aberrations, internal astigmatism, and corneal biomechanical properties and to define a new grading system based on visual limitation.
Setting: Vissum Corporation, Alicante, Spain.
Design: Retrospective case series.
Purpose: To determine if superficial lamellar corneal excision with femtosecond laser followed by phototherapeutic keratectomy (PTK) using a masking substance improves visual acuity and optical quality of patients with severe corneal opacities.
Methods: Twelve eyes with corneal haze or scarring underwent confocal microscopy to estimate the opacities' thickness and calculate the excision depth. Femtosecond laser was then used to create a superficial corneal flap.
