Myopia: radial keratotomy versus excimer laser.

Myopia can be treated by radial keratomy or by excimer laser. RK is an already old procedure, excimer laser photoablation being relatively new. It is not clear which modality will best help the patient. To make up our minds, we took a sample of 8 patients, in whom we treated the first eye by RK, the second by laser. This experiment started in January 1992. Those patients were checked on anamnesis, refraction, electronic keratoscopy and follow-up. Anamnestically, every patient preferred the speed of recovery and the brightness of the sight in the RK eye and wondered why we treated the second eye with the laser. Our current attitude is to perform RK in every patient except where a bad RK-result is to be expected (high myopes, low eyepressure, very young patient, etc.), where we advise our excimer (Preference 20 to 1).

Radial keratotomy.

The author describes his experience after thirteen years of radial keratotomy. Indications, principles, results, prognosis and complications are evaluated.

[4-incision keratotomy: Saint Andrew's cross or the Greek cross?].

For low to moderate myopes (-1.50 to -4.50) having a four-incisions keratotomy, the authors compare the disposition of the cuts: like a "x" in one eye or like a "+" in the opposite eye. Visual acuity, pre- and postoperative keratometry and the evaluation of astigmatism are necessary to establish the efficacity of these "crosses".

Patient preference--contact lens or radial keratotomy?

BACKGROUND: Past clinical experience has suggested that patients are more satisfied after radial keratotomy than when wearing contact lenses. METHODS: One-hundred patients who had worn contact lenses prior to receiving radial keratotomy compared subjectively these two methods for correcting myopia. The postoperative follow up ranged from 3 months to 13 years. RESULTS: The vast majority (93%) preferred radial keratotomy to the handling of contact lenses. CONCLUSIONS: The desire to be independent of optical correction is a sufficient indication for refractive surgery.

Assessing the efficacy of topical corticosteroids following radial keratotomy.

BACKGROUND: The postoperative use of topical corticosteroids may decrease the risk for regression and thereby improve the refractive outcome following radial keratotomy. METHODS: Twenty patients with identical preoperative refractions in each eye underwent bilateral radial keratotomy in one sitting. One eye was treated with dexamethasone twice daily for 3 months postoperatively; the fellow eye was not. RESULTS: Three months postoperatively, there was no difference between the refractions of the two groups of eyes. CONCLUSION: The use of topical dexamethasone after radial keratotomy for 3 months does not improve the refractive outcome.
