For laser-assisted in situ keratomileusis (LASIK) retreatments with a previous unsuccessful mechanical microkeratome-assisted surgery, some surgical protocols have been described as feasible, such as relifting of the flap or the creation of a new flap and even the change to a surface ablation procedure (photorefractive keratectomy (PRK)). This case shows the use of femtosecond technology for th...

OBJECTIVE To compare 3 techniques used for removing the recipient stroma during anterior lamellar keratoplasty (ALK): the "big-bubble" technique, manual dissection using a crescent blade and slitlamp operating microscope, and microkeratome lamellar cut. DESIGN Retrospective comparative cohort study of 69 consecutive ALKs and 69 consecutive penetrating keratoplasties (PKs). Manifest refraction...

PURPOSE To describe the preparation and thickness profiles of endothelial keratoplasty lenticules harvested from eyes with previous photorefractive keratectomy (PRK). METHODS Donor whole eyes that underwent PRK were subjected to microkeratome-assisted dissection for Descemet stripping automated endothelial keratoplasty. Specular microscopy and Visante optical coherence tomography were perform...

We evaluate the efficacy and safety of Keraring 355° intrastromal corneal ring segment (ICRS) implantation aided by PocketMaker microkeratome for the correction of keratoconus. Patients underwent ICRS insertion using mechanical dissection with PocketMaker microkeratome and completed 6 months of follow-up. Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), refracti...

PURPOSE To determine the effect of different blades on laser in situ keratomileusis (LASIK) flap thickness created with the Amadeus I microkeratome (Ziemer Ophthalmic Systems). SETTING Emory University Department of Ophthalmology and Emory Vision, Atlanta, Georgia, USA. METHODS This retrospective nonrandomized comparative case study from January 2005 through June 2006 compared LASIK flap th...

BACKGROUND A new technique, therapeutic alloplastic laser in situ keratomileusis to correct high myopia, is introduced. METHODS Therapeutic alloplastic laser in situ keratomileusis consists of neutral homoplastic epikeratoplasty combined with superficial keratectomy performed with an excimer laser and/or a microkeratome. Indications for the technique are: myopia over 20 diopters (D), eyes wit...

PURPOSE To compare three microkeratome-assisted techniques for the preparation of ultrathin (UT) grafts for Descemet stripping automated endothelial keratoplasty. METHODS After dissection with a 300-μm microkeratome head in 40 donor tissues, a second cut was performed with a 130-μm head either after manual stromal hydration (group A, n = 10) or osmotic hydration at the eye bank (group B, n = ...

PURPOSE To compare stromal surface and endothelial morphology after keratectomies and after laser in situ keratomileusis (LASIK), using two different microkeratomes. METHODS Keratectomies (160-microm and 400-microm) were performed on 82 enucleated porcine eyes using the Chiron Automated Corneal Shaper (52 eyes) and the Microtech Turbokeratome (30 eyes). LASIK procedures of -9.00 D, -27.00 D, ...

PURPOSE To describe the incidence, management, and visual outcomes of buttonholed laser in situ keratomileusis (LASIK) flaps. SETTING Private practice, Riyadh, Saudi Arabia. METHODS This retrospective review identified eyes that developed buttonholed flaps during LASIK. Preoperative, intraoperative, and postoperative data were obtained to identify factors predictive of this complication. ...

PURPOSE To harvest microorganisms from the microkeratome after LASIK. To induce experimental infectious keratitis and investigate the use of routine postoperative medication. METHODS During eight consecutive days, we cultured the plate of the microkeratome after routine LASIK. Dilutions of the most frequent microorganism was prepared according to the MacFarland scale. Ten microliters were inj...
