The old way of correcting myopia!

⁣ Radial Keratotomy⁣ ⁣ Radial Keratotomy is a refractive surgery procedure to correct myopia⁣ ⁣ Developed in 1974 by Svyatoslav Fydorov⁣ ⁣ It is now obsolete and has been replaced by laser based refractive surgery procedures such as Photorefractive Keratectomy (PRK) and LASIK⁣



⁣ Incisions:⁣ ⁣ ● Series of 4-8 deep radial corneal stromal incisions in a spoke like pattern⁣ ⁣ ● Starting from central optical zone (4mm) till the limbus in the mid-peripheral and peripheral cornea⁣ ⁣ ● Approximately 90% of depth of the cornea⁣ ⁣ ● Mid-periphery of cornea bows anteriorly, weakens paracentral and peripheral cornea and flattens the central cornea thus correcting myopia⁣ ⁣ Basic steps:⁣ ⁣ 1) Application of anaesthesia⁣ 2) Marking the visual axis⁣ 3) Marking the optical zone⁣ 4) Measuring the corneal thickness 5) Setting the depth of the blade⁣ 6) Marking the corneal incisions ⁣ ⁣ Complications:⁣ ⁣ ● Corneal perforation (micro or macro)⁣ ● Incisions across visual axis - glare, astigmatism, scarring⁣ ● Decentration of incisions⁣ ● Overcorrection⁣ ● Undercorrection⁣ ● Astigmatism⁣ ● Infectious keratitis⁣ ● Traumatic rupture of keratotomy scars⁣ ⁣ www.ophthalmobytes.com⁣ ⁣ Image from Rajan Eye Care Hospital ⁣ #ophthalmology #ophthal #doctor #health #medical #vision #education #optometry #medicalstudent #optometrist #medicine #eye #ophtho #ophthalmologist #ophthalmo #med #medicaleducation #ophthalmologyresident #ophthalmologyresidency #refractivesurgery #cornea #radialkeratotomy #LASIK #myopia
