Radial Keratotomy

10/10/1991 - "At present, correction of myopia is accomplished with radial keratotomy (RK), a procedure that achieves the best results in the range up to - 6.0 diopters. "
01/01/1997 - "MLK is effective in high myopia treatment and has some special advantages compared with radial keratotomy, photorefractive keratectomy, automated lamellar keratoplasty and excimer laser in situ keratomileusis. "
01/01/1996 - "Radial keratotomy for low myopia can produce good results with few side effects. "
01/01/1990 - "Radial keratotomy is effective for correcting low-grade myopia. "
04/02/1988 - "It is shown that, although radial keratotomy is effective in the low-to-moderate myopia group, its effect in individual eyes is not totally predictable."

07/01/2012 - "Topography-guided ablations demonstrate good outcomes for the correction of astigmatism after penetrating keratoplasty, laser-assisted in-situ keratomileusis (LASIK) flap or interface complications, post-radial keratotomy eyes, and other highly aberrated corneas, many of which are poor candidates for wavefront-guided therapy. "
01/01/2022 - "Topography-guided photorefractive keratectomy improved vision-related quality of life in patients with a history of irregular astigmatism secondary to radial keratotomy."
07/01/2022 - "The aim of this study was to evaluate the visual acuity and satisfaction after IC-8 implants in patients characterized by corneal irregularities and HOAs who could not undergo refractive surgery due to the poor residual thickness of the cornea or other conditions such as astigmatism secondary to previous radial keratotomy. "
04/01/2022 - "Accuracy of astigmatism correction with toric intraocular lens implantation in eyes with previous radial keratotomy."
01/01/2022 - "Vision Quality Questionnaire Assessment in Patients After Topography-Guided Photorefractive Keratectomy for Irregular Astigmatism Secondary to Radial Keratotomy."

08/01/2001 - "Laser in situ keratomileusis has proved to be an effective treatment for correction of residual refractive errors after radial keratotomy. "
07/01/2011 - "To evaluate the safety and efficacy of laser in-situ keratomileusis (LASIK) in eyes with residual/induced refractive error following radial keratotomy (RK). "
09/01/2002 - "This prospective convenience sample study included 3 groups: 3 patients who had had bilateral myopic radial keratotomy (RK); 2 who had had bilateral myopic laser in situ keratomileusis (LASIK); and 4 control subjects who had no previous corneal refractive surgery or ocular pathology but had a myopic refractive error (-1.25 to -8.38 diopters [D]) similar to that in the treated patients before refractive surgery. "
02/01/1996 - "The authors determine whether diurnal change in refractive error persists 11 years after radial keratotomy surgery in the Prospective Evaluation of Radial Keratotomy (PERK) study. "
05/01/1993 - "The study offers this as one reason that radial keratotomy patients with residual refractive error often have better uncorrected visual acuity than expected."

01/01/1992 - "No effective treatment for hyperopia following radial keratotomy has been described. "
03/02/2000 - "LASBK for induced hyperopia after radial keratotomy is safe and effective, without vision-threatening complications. "
01/01/2020 - "Progressive hyperopia development in the long-term period after radial keratotomy (RC) is associated with not only surgical effects, but also individual biomechanical features of the fibrous tunic of the eye, its age-related changes, and hydrodynamic disturbances. "
01/01/2020 - "[On the question of progressive hyperopia correction after radial keratotomy]."
01/01/2016 - "The charts of 27 eyes of 18 patients who underwent femtosecond laser-assisted LASIK with the WaveLight FS200 laser (Alcon Laboratories, Inc., Fort Worth, TX) for consecutive hyperopia following previous radial keratotomy were retrospectively reviewed at a single private practice location. "

11/01/1995 - "We designed a study to evaluate healing in reopened-and-sutured (RAS) keratotomy wounds to determine the efficacy of reoperations in treating radial keratotomy overcorrections. "
03/01/1996 - "Our study suggests that the peripheral "tissue addition" seen after radial keratotomy is a net result of wound gape and circumferential tissue compression. "
08/01/1995 - "RESULTS AND STATEMENTS: For comparison of refractive surgery of the cornea not only the PERK study and the recommendations of the American Academy of Ophthalmology have to be considered, but also the newest developments in radial keratotomy such as two-step incision and reoperation with reopening of the keratotomy wounds. "
08/01/1995 - "This study aimed to evaluate stromal wound healing morphology in short term unsutured compared with sutured corneal wounds, to define regional variation in healing within radial keratotomy wounds. "
07/15/1985 - "We studied corneal wounds with a slit-lamp microscope as they healed from two weeks to three years after radial keratotomy in 84 eyes of 51 consecutive patients enrolled in the Prospective Evaluation of Radial Keratotomy (PERK) Study. "
