145. Current trends in pain management after photorefractive and phototherapeutic keratectomy. (PubMed)

Current trends in pain management after photorefractive and phototherapeutic keratectomy. Since the introduction of photoablative procedures, postoperative pain management has been a major challenge for both the patient and the surgeon. Over the years, significant advances have been made in our ability to overcome this challenge. The purpose of this article is to discuss the most current strategies for pain control after photorefractive keratectomy and phototherapeutic keratectomy.Methods (...) for pain control can be targeted locally or systemically and can be pharmacological or nonpharmalogical. Options include anesthetics, NSAIDs, opiates, and anticonvulsants, as well as bandage contact lenses and corneal cooling.Literature and experience provide insight on the efficacy and safety of the many options for post-photorefractive keratectomy pain control. Generally, refractive surgeons are using a combination approach to achieve pain control with excellent results.

154. Application of cold patch in relieving pain after transepithelial photorefractive keratectomy. (PubMed)

Application of cold patch in relieving pain after transepithelial photorefractive keratectomy. A return toward toward photorefractive keratectomy has occurred due to better corneal stability and fewer corneal flap complications; however, pain remains a major drawback of the procedure. Currently, clinical pain control measures focus on the administration of pain medications, which may delay corneal epithelial healing and has, occasionally, led to serious corneal toxicity.To investigate (...) the safety and efficacy of a cold patch on postoperative pain and other relevant consequences of transepithelial photorefractive keratectomy.A prospective, randomized controlled study was conducted. Forty patients (80 eyes) scheduled to undergo transepithelial photorefractive keratectomy for myopia or myopic astigmatism were randomly and equally assigned to be treated with ice-cold balanced salt solution during surgery (wash group) or to wear a postoperative cold patch on the eye for 24 h.
