Epikeratophakia for the treatment of hyperopia.

Nordan epikeratophakia technique (NET) is described for the treatment of hyperopia and the results in eight eyes are reported (mean = +5.09 +/- 0.85 diopters preoperatively and -2.09 +/- 1.22 diopters postoperatively). The Nordan epikeratophakia technique is a modification of Kaufman-McDonald epikeratophakia with advantages that are described. Data are analyzed according to traditional means in addition to newer indices that consider both the uncorrected visual acuity and the refractive error.

Quantifiable astigmatism correction: concepts and suggestions, 1986.

Astigmatism control and correction is of great concern to refractive, cataract, and corneal surgeons. This paper presents a systematic surgical approach to astigmatism based on my experience. Concepts to improve predictability of astigmatic keratotomy are offered for consideration.

Trapezoidal relaxing incision for post keratoplasty astigmatism.

Eleven patients with high astigmatism after penetrating keratoplasty underwent a new form of relaxing keratotomy, the trapezoidal relaxing keratotomy, originally described by Ruiz. The average preoperative astigmatism was 7.89 diopters (range 4.25 to 12.50 diopters) with an average reduction in cylinder of 5.00 diopters (range 0-9.5 diopters). No complications were experienced.

Hazards of bilateral intraocular lens implantation.

Seven patients had bilateral intraocular lens implantation performed with a short interval between procedures, using intraocular lenses of unproven design or deficient quality control All seven patients suffered severe visual impairment, some to the level of legal blindness in both eyes. Lenses with unproven design characteristics should never be implanted in both eyes of a patients. The interval between the first and second procedure, even when using lenses of proven design and quality, should be long enough to insure the long-term successful outcome of the first procedure.
