Situations, where that may arise, include keratoconus, for example. If a cornea is particularly distorted or sometimes if a patient has had laser refractive surgery in the past, LASIK, for example, additional tests will help to optimize the outcome.
Once all those tests have been done, the strength of lens that’s required to be implanted in the eye and calculating any correction for astigmatism should take care of near-sightedness, long-sightedness and astigmatism, all in one procedure.
A small proportion of patients, if they don’t achieve the perfect outcome that was planned proactively, may require a laser refractive procedure to correct and enhance their outcome–but that’s very unusual.
I invite you to book a consultation to determine your suitability for refractive cataract surgery or refractive lens exchange. It’s the only way to determine your suitability for these procedures and to have an in-depth discussion regarding the risks and benefits of each of them. I look forward to seeing you there and taking you through the journey to achieving your desired postoperative outcome.
