Purpose: To study the outcomes of LASIK after intended thin flap creation using the SCHWIND Carriazo-Pendular microkeratome with the 90-microm head.
Methods: Forty-seven eyes of 26 patients (mean age 28.78+/-6.98 years) underwent LASIK with a superior hinge flap using the 90-microm head of the SCHWIND Carriazo-Pendular microkeratome. Evaluation included flap parameters (thickness, diameter, hinge size), complications, and visual outcome.
Results: No intraoperative or early postoperative complications were observed. The mean flap thickness was 79.88+/-6.94 microm (range: 70 to 93 microm). Mean flap diameter was 9.25+/-0.45 mm (range: 8.5 to 11 mm) whereas mean hinge size was 4.63+/-0.66 mm (range: 3 to 6.5 mm). No eye lost lines of best spectacle-corrected visual acuity, and all eyes were emmetropic within one diopter postoperatively.
Conclusions: The SCHWIND Carriazo-Pendular microkeratome with the 90-microm head seems to have increased accuracy in intended creation of thin flaps.

Laser in situ keratomileusis for high hyperopia with corneal vertex centration and asymmetric offset.

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. Eyes targeted for plano and with correction in the maximum hyperopic meridian strictly higher than +4D were included in the retrospective analysis.
Purpose: To investigate refractive outcomes and induction of corneal higher order aberrations (HOAs) in eyes with large pupil to corneal vertex offset that underwent LASIK for hyperopia using an aberration-neutral profile with corneal vertex centration and asymmetric offset.
Methods: In this retrospective consecutive review, 26 patients (46 eyes) who underwent LASIK performed by one surgeon using the AMARIS 750S excimer laser platform and Carriazo-Pendular microkeratome (both from SCHWIND eye-tech-solutions, Kleinostheim, Germany) for flap creation were retrospectively analyzed. Only eyes targeted for plano and with a pupil to corneal vertex offset greater than 200 µm were included.

Article Synopsis
- Femtosecond lasers are commonly used for LASIK flap creation, but the SCHWIND Carriazo-Pendular microkeratome presents a cost-effective alternative worth exploring.
- An experimental study evaluated the impact of different cutting parameters on LASIK cuts using this microkeratome on porcine eyes, assessing the results through scanning electron microscopy.
- Findings suggest that while cutting parameters like oscillation frequencies did not significantly affect quality, deeper cuts and an optimal oscillation/feed rate ratio improved cut smoothness and edge sharpness, confirming the microkeratome's safety and effectiveness as an option for LASIK flap creation.
Purpose: to compare visual, refractive, and wavefront aberration outcomes of laser epithelial keratomileusis (LASEK), thin-flap LASIK (flap thickness 110 to 130 microm), and ultrathin-flap LASIK (flap thickness <110 microm) after excimer laser ablation with an aspheric ablation profile.
Methods: a retrospective analysis of 97 eyes of 56 patients with myopia <6.00 diopters (D) sphere (30 eyes, alcohol-assisted LASEK; 30 eyes, LASIK 110; and 37 eyes, LASIK 130) was conducted.
Interface Haze Formation After Ultra Thin Flap Laser in Situ Keratomileusis.
Ophthalmic Surg Lasers Imaging
March 2010
In this case series, five patients (10 eyes) underwent laser in siter keratomileusis (LASIK) for the correction of moderate myopia and astigmatism with the Schwind Carriazo Pendular microkeratome 90 mum head. Flap (superior hinged) thickness measured intraoperatively was assessed less than 70 mum in all eyes. On first month's postoperative examination, subepithelial mild corneal haze with consequent myopic regression was found in all patients.
