“… 36 RK yields acceptable refractive results with 60% of patients within 1 diopter of the intended result. 35 , 37 On the other hand, RK can lead to a progressive overcorrection and resulting hypermetropia. As a result of this shortcoming and with the rise of modern laser-based refractive procedures, RK has been used less frequently from the mid-1990s onwards.…”

Intraocular lens (IOL) power calculation after corneal refractive surgery (CRS) becomes an expanding challenge for ophthalmologists as more and more cataract surgeries after CRS are required. These patients typically also have high expectations as to visual performance. Conventional IOL power calculation schemes frequently provide inaccurate results in these cases. This review aims to summarize and recommend currently available IOL power calculation methods for eyes with the most common CRS methods: radial keratotomy (RK), photorefractive keratectomy (PRK), laser in situ keratomileusis (LASIK), and small incision lenticule extraction (SMILE). To this end, biometry measuring methods and IOL formulas will be explained and combinations of both are proposed. In synopsis, it is evident that the latest generation of vergence formulas exhibit favorable IOL power prediction accuracy in post-CRS eyes, even though the predictive precision of methods in eyes without CRS is not attained. Ray tracing computation, intraoperative aberrometry, and machine learning–based formulas hold potential to further improve refractive outcomes in post-CRS eyes.

“…The procedure works reasonably well for low degrees of myopia. A prospective study of the procedure set up in the 1980s and followed for 10 years showed 60% of patients were within 1 dioptre of the intended result, and that uncorrected visual acuity was 20/20 in 53% of patients, and 85% of patients had 20/40 or better2; a more recent study with modified techniques showed some improvement in results 32 and since the advent of excimer laser treatment, radial keratotomy is used less frequently.…”

Refractive surgery, par excellence, is the ophthalmic surgery of the end of the millennium. This type of surgery is performed mostly for non-sight threatening conditions; it frequently involves high technology such as lasers and computers; the great majority of this type of surgery is done in the developed world; patients have very high expectations of the surgery and want very detailed explanations about results and complications; and there is a burgeoning medicolegal industry linked to the outcome of refractive surgery.All these aspects of refractive surgery are starting to be echoed to a greater or lesser extent in many other areas of ophthalmic surgery. To give an example, the concept of detailed informed consent, and linked with it, the use of very lengthy and explicit consent forms, information leaflets, and educational videos are ideas which first appeared extensively in refractive surgery, but are now spreading to other areas of ophthalmology. So if we want to have a feel for the way ophthalmology is going to be going in the next millennium then we need look no further than refractive surgery today.
