The usual tendency of an increase in "against the rule astigmatism" that occurs when PK alone is done for PMD was eliminated.Ĭustomized ultra-high-power toric intraocular lens implantation for pellucid marginal degeneration and cataract. Low to moderate levels of postkeratoplasty astigmatism were achieved in all the eyes treated. The short-term results with this technique are excellent in that it provides early and stable visual rehabilitation in patients with advanced PMD. Two patients had elevations of intraocular pressure that responded to reduction in topical steroid dose. A tendency for an increase in "with the rule astigmatism" after the rehabilitation period was noted. The time required for visual rehabilitation ranged from 5.13 to 10.93 (mean, 9.92) months, and the amount of corneal astigmatism at the end of this period ranged from 0.3 diopters (D) to 5.3 D. The latter two had decreased acuity from posterior subcapsular cataract formation, which may have been caused by topical steroid use. Visual acuity results were 20/40 in three eyes, 20/80 in one eye, and 20/400 in one eye. Measuring the change in corneal astigmatism by videokeratography over the subsequent follow-up period after spectacle correction had been prescribed assessed stability of the achieved refraction. These included interval of time required for visual rehabilitation, best spectacle-corrected visual acuity achieved, and amount of corneal astigmatism, as measured by videokeratography. Simultaneous peripheral crescentic LK and central PK followed by selective suture removal and astigmatic keratotomy in the postoperative period. Retrospective, noncomparative, interventional case series. To determine the efficacy of simultaneous peripheral crescentic lamellar keratoplasty (LK) and central penetrating keratoplasty (PK) for advanced pellucid marginal degeneration (PMD). Surgical treatment of advanced pellucid marginal degeneration. Although the results are encouraging, concern still exists regarding the long-term effect of this approach for the management of patients with PMD. Corneal topographic pattern also improved. Eleven months after the procedure, the uncorrected visual acuity was 20/200, compared with counting fingers preoperatively, while the best spectacle-corrected visual acuity improved to 20/25 from 20/50. Two Intacs segments (0.45 mm thickness) were inserted uneventfully in the fashion typically used for low myopia correction (nasal-temporal). Kymionis, George D Aslanides, Ioannis M Siganos, Charalambos S Pallikaris, Ioannis GĪ 42-year-old man had Intacs (Addition Technology Inc.) implantation for early pellucid marginal degeneration (PMD). Intacs for early pellucid marginal degeneration.
