Twelve months postoperatively, the BSCVA improved significantly, the lines of vision increased, and astigmatism, corneal best-fit sphere, mean keratometry, corneal thickness, corneal root mean square total, and corneal spherical aberrations decreased. TG-PRK with MMC is a good alternative for correcting post-PKP cases with irregular astigmatism with elevated higher-order aberrations.

We report the results of using the small-diameter corneal inlay to create a bifocal cornea. The inlay was implanted in five eyes in January 1993. At 12 months postoperatively, uncorrected near vision had improved from J4 to better than J2 in four of the five. The results indicate that the corneal inlay improves near vision and is compatible within the cornea.

Photorefractive keratectomy was efficacious in correcting residual myopia after RK in a group of selected patients.

We present 3 eyes that underwent photorefractive keratectomy (PRK) for residual myopia after penetrating keratoplasty, and 1 eye that was treated for recurrent granular dystrophy and myopia following penetrating keratoplasty. The 3 refractive eyes experienced improvements in visual acuity and refractive error through 3 months postoperative, but exhibited regression of effect after 6 months postoperative. One eye also exhibited substantial corneal haze at three months postoperative that was not responsive to steroid retreatment. The eye with granular dystrophy obtained symptomatic relief as well as improvement in vision. We tentatively conclude that the corneal transplant reacts to photorefractive keratectomy in much the same way as a normal cornea. Eyes with substantial degrees of post-graft myopia exhibit regression of refractive effect, much like high myopes following primary photorefractive keratectomy. Photorefractive was unable to prevent the recurrence of granular dystrophy in the transplanted tissue. The eyes reported here achieved only modest long-term visual and refractive improvements.

A 31-year old female underwent lamellar keratoplasty for the treatment of bilateral primary familial amyloidosis of the cornea in 1983 (OS), 1986 (OD), and 1989 (OS). The lesions recurred bilaterally and visual acuity in 1992 was 20/400 in each eye. After debridement of essentially all corneal epithelium, the entire cornea of the left eye was treated with excimer laser phototherapeutic keratectomy (PTK). One month postoperatively, visual acuity was 20/50 and the corneal surface appeared smooth and clear with no evidence of recurrence. Four months postoperatively, the patient continued to be free of recurrence. (Refract Corneal Surg (suppl) 1993;9:S138-S141.)
