  4. Article: Microkeratome-assisted mushroom keratoplasty with minimal endothelial replacement.

    Abstract Purpose: To report the outcome of a new keratoplasty technique aimed at treating full-thickness opacities with minimal removal of recipient endothelium.
    Design: Interventional case report.
    Methods: A deep central scar was removed using microkeratome-assisted mushroom-shaped keratoplasty, consisting of a large anterior stromal lamella (9.0-mm in diameter) and a small posterior button (5.0-mm in diameter) including deep stroma and endothelium. Complete suture removal was performed 3 months after surgery. Visual acuity, refraction, and computerized corneal topography were evaluated pre- and postoperatively.
    Results: Best spectacle-corrected visual acuity improved from 20/60 to 20/20 at 6 months postoperatively. Postoperative refraction was -2.50-1.00 x 20 degrees.
    Conclusions: Microkeratome-assisted mushroom keratoplasty may offer visual and refractive advantages over conventional keratoplasty surgery. Because most of the recipient endothelium is preserved and may spread onto the posterior surface of the small donor button, graft decompensation secondary to immunologic rejection may be avoided with this technique.

    Abstract Purpose: To evaluate the effect of a new suturing technique on postkeratoplasty visual rehabilitation time and refractive error.
    Methods: Penetrating keratoplasty was performed on 17 eyes with keratoconus using a modified suturing technique. A donor button 8.0 mm in diameter was sutured into a 7.75-mm recipient bed with both deep and superficial sutures. The deep sutures consisted of either a single 16-bite 10-0 nylon running suture (n = 7) or eight interrupted 10-0 nylon cross-stitches (n = 10). These sutures were passed into the mid-stroma of the donor cornea and exited through the donor endothelium, then passed through the endothelium of the recipient cornea and exited from its mid-stroma. Thereby all parts of the deep sutures remained below the corneal surface. To further secure the surgical wound, in each case a running 16-bite 10-0 nylon superficial suture was also placed. Care was taken to maintain the bites of the superficial suture above the level of the deep sutures. The superficial suture was removed 3 months after surgery. Vision and refraction were recorded 1 day and 1 month postoperatively and 1 and 3 months after suture removal. A paired Student test was used to verify the significance of changes in visual acuity and refraction recorded at different examination times.
    Results: As early as 1 month after surgery, spectacle best-corrected visual acuity 20/40 or more and refractive astigmatism less than 4 diopters (D) were recorded in each eye and maintained with two exceptions at the later examination times. In two patients, postoperative astigmatism increased from 4.5 to 5 D after suture removal.
    Conclusions: Deep suturing allowed quick visual rehabilitation while minimizing postkeratoplasty astigmatism in the patients with keratoconus operated on in this series.

  6. Article ; Online: Microkeratome-assisted lamellar keratoplasty for the surgical treatment of keratoconus.

    Abstract Purpose: To evaluate the visual and refractive results of microkeratome-assisted lamellar keratoplasty (LK) performed on keratoconus patients intolerant to spectacles and contact lenses.
    Design: Prospective, noncomparative, interventional study.
    Participants: A microkeratome-assisted LK procedure was performed on 50 eyes of 50 keratoconus patients. All patients were spectacle and contact lens intolerant.
    Intervention: All patients included in this study underwent a standard surgical procedure involving removal of a lamella (9 mm in diameter cut with the 250-microm microkeratome head) from the recipient cornea by means of a hand-driven microkeratome and suturing of a donor lamella (0.5 mm smaller in diameter than the removed corneal lamella, cut with the 350-microm microkeratome head) obtained from a cornea mounted on an artificial anterior chamber. Each patient was examined preoperatively and at different postoperative times (1 and 6 months and 1, 2, 3, and 4 years).
    Main outcome measures: Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), 1-year best contact lens-corrected visual acuity (BCLCVA), refraction, and computerized analysis of corneal topography.
    Results: After suture removal was completed, both UCVA and best-corrected visual acuity were significantly improved over properative values at all examination times. One year postoperatively, when follow-up was still available for all patients, UCVA was better than 20/200 in 8 of 50 (16%) patients and BSCVA was > or =20/40 in 44 of 50 (88%) patients, whereas BCLCVA was > or =20/40 in all 50 patients. Refractive astigmatism within 4 diopters was seen in 43 of 50 (86%) patients. Corneal topographic patterns were classified as regularly astigmatic in 39 of 50 (78%) patients. The 1-year values did not change substantially at later postoperative examination times. Complications included preparation of donor grafts of poor quality that needed to be discarded (8 cases [16%]), irregular astigmatism of various degrees (11 cases [22%]), high-degree astigmatism requiring secondary intervention (6 cases [12%]), epithelial interface ingrowth (1 case [2%]), and cataract formation (1 case [2%]).
    Conclusions: Microkeratome-assisted LK can be performed on corneas with moderate to advanced keratoconus with a minimal corneal thickness of >380 microm. The procedure is relatively simple, may be standardized in most of its parts, and does not involve time-consuming maneuvers. All complications recorded did not threaten vision and were dealt with successfully. Our results indicate that microkeratome-assisted LK is as efficacious as conventional penetrating keratoplasty for the surgical treatment of keratoconus. However, the time necessary to achieve stable results is considerably shorter.

    Abstract Purpose: To report a case of interface infection by Mycobacterium chelonae in a patient who underwent endokeratoplasty.
    Design: Interventional case report.
    Setting: Clinical practice.
    Methods: Two weeks after endokeratoplasty, a 74-year-old woman developed multiple enlarging interface infiltrates in her right eye. Cultures performed on the preservation medium grew Mycobacterium chelonae. Penetrating keratoplasty (PK) surgery was performed after failure of conservative antibiotic therapy, including topical and systemic clarithromycin.
    Results: Five months after PK surgery, the graft was clear and no signs of extraocular or intraocular inflammation were present. Cultures taken from the corneal interface at the time of PK surgery confirmed the presence of M. chelonae. Acid-fast bacilli were seen in the excised corneal button.
    Conclusions: M. chelonae should be ruled out as a possible etiologic agent when postoperative infection of the corneal interface occurs. Surgical intervention can lead to eradication of the infection when conservative treatment fails.
