AI Article Synopsis
- The study examined the effectiveness of radial keratotomy as a treatment for undercorrections after photorefractive keratectomy in myopic patients.
- Twenty myopic eyes were initially treated with Excimer laser and showed a mean myopic refraction of -2.20 after a follow-up period of about 16 months.
- Results indicated significant improvement in visual acuity and reduced refractive error following radial keratotomy, confirming it as a safe and reliable option for this type of correction.
Article Abstract
Background: Effectiveness of radial keratotomy for undercorrections following photorefractive keratectomy.
Methods: Twenty myopic eyes from minus 4.75 to minus 8.25 were treated by Excimer laser photorefractive keratectomy and regressed to a mean myopic refraction of minus 2.20 +/- 0.81 after a follow-up of 10 to 22 months (mean: 16.25). Radial keratotomy was performed using Hoffmann Fyodorov Thornton nomogram. Blade depth was set according to pachymetry performed before surgery under microscopic examination, paracentrally on the meridian of each incision.
Results: Postoperative results were evaluated after 6 to 20 months follow-up. After radial keratotomy mean refractive error was minus 0.30 +/- 0.43 and minus 0.32 +/- 0.25 at 3-6 and 6-12 months respectively. Visual acuity, without correction, was prior to radial keratotomy: 2.18 +/- 0.99; 8.125 +/- 0.6 at 3-6 months and 8.43 +/- 1.57 at 6-12 months after radial keratotomy.
Conclusion: Radial keratotomy appears to be a safe, simple and predictible technique to treat undercorrections following Excimer laser photokeratectomy.

A woman in her early 50s presented with diminution of vision, photophobia, pain and watering in right eye for 8 months. She had previously undergone radial keratotomy (RK) in the right eye, followed by bilateral angle-supported phakic intraocular lens (pIOL) implantation. On examination, 16 RK incisions were present in the right eye, with corneal decompensation, rigid angle-supported pIOL in situ, senile cataract and uncorrected distance visual acuity (UDVA) of counting fingers.

Department of Ophthalmology, University of California San Francisco, San Francisco, CA.
Purpose: To report a case of Light Adjustable Lens (LAL, RxSight, Aliso Viejo, CA) implantation in a patient with bilateral 50-cut radial keratotomy (RK) and discuss related preoperative, intraoperative, and postoperative considerations.
Methods: A 78-year-old patient with history of bilateral 50-cut RK underwent phacoemulsification with implantation of LALs in both eyes one month apart. Although LAL technology was not approved specifically for addressing limitations in intraocular lens calculation post-RK due to corneal topography irregularity, the patient opted for this lens due to its ability to make post-operative adjustments to its refractive power.
Visual Outcome and Patient Satisfaction with Implantation of Trifocal Intraocular Lens After Radial Keratotomy.

Anterior Segment Division, Kahhal Medical Centre, Dammam, Saudi Arabia.
Objective: To investigate the visual outcomes and patient satisfaction following trifocal intraocular lens (IOL) implantation after radial keratotomy (RK).
Methods: This was a retrospective chart review wherein we studied 14 eyes from 7 patients who had undergone cataract surgery and had trifocal intraocular lens (IOL) implanted in the Eastern Province of Saudi Arabia's King Fahd University Hospital and Kahhal private centre. Data such as demographic characteristics, the time between RK and cataract removal, intraoperative and postoperative complications, preoperative and postoperative uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and refraction were evaluated.
