Case report: femtosecond laser-assisted small incision deep lamellar endothelial keratoplasty.

Lee DH, Chung TY, Chung ES, Azar DT - Korean J Ophthalmol (2008)

Bottom Line: In Case 1, the graft was clear and compact without interface haze, Orbscan showed smooth and regular corneal surface, specular microscopy was unremarkable without sign of corneal endothelial damage, and Optical coherence tomography showed uniform graft well attached to recipient stroma with minimal interface reflection at 2 months postoperation.In Case 2, the graft was clear and compact with minimal interface haze at 1 month postoperation.Femtosecond laser-assisted small incision DLEK was safe and technically feasible in our cases; however, further evaluation is required to determine long-term effects.

ABSTRACT

Purpose: To report two cases of femtosecond laser-assisted small incision deep lamellar endothelial keratoplasty (DLEK) for patients with corneal endothelial decompensation by Fuchs dystrophy and glaucoma

Methods: Femtosecond laser (IntraLase; IntraLase Corp., Irvine, CA) with 15 kHz of repetition rate, was used for a 9.5 mm diameter by 400 micrometer thickness donor corneal lamellar dissection.

Results: In Case 1, the graft was clear and compact without interface haze, Orbscan showed smooth and regular corneal surface, specular microscopy was unremarkable without sign of corneal endothelial damage, and Optical coherence tomography showed uniform graft well attached to recipient stroma with minimal interface reflection at 2 months postoperation. In Case 2, the graft was clear and compact with minimal interface haze at 1 month postoperation. Femtosecond laser-assisted small incision DLEK was safe and technically feasible in our cases; however, further evaluation is required to determine long-term effects.

Figure 1: Preoperative photograph of a 73-year-old male showing corneal edema and guttata with beaten metal appearance (A). Specular microscopy shows coalesced guttata excrescences in the form of dark structures (cell density 1363 cell/mm2, coefficient of variation 0.44, hexagonality 54%) (B).

Mentions: Femtosecond laser-assisted small incision DLEK was performed in the right eye of a 73-year-old male with Fuchs dystrophy (Fig. 1). Preoperative uncorrected visual acuity (UCVA) and best spectacle corrected visual acuity (BSCVA) was 20/100 and 20/80 respectively and manifest refraction was +0.75 -1.75×30. Table 2 summarizes the clinical data. Donor corneoscleral button lamellar dissection was performed using IntraLase femtosecond laser (IntraLase Corp.), set at a depth of 400 µm and flap diameter of 9.5 mm. Surgery was performed as described above.
