Conductive keratoplasty (CK) is a type of refractive surgery that uses radio waves to adjust the contour of the cornea by shrinking the corneal collagen around it. [1] It is used to treat mild to moderate hyperopia.
LASIK surgery is performed by an ophthalmologist who uses a femtosecond laser or a microkeratome to create a corneal flap to expose the corneal stroma and then an excimer laser to reshape the corneal stroma in order to improve visual acuity. [2] [3] LASIK is very similar to another surgical corrective procedure, photorefractive keratectomy (PRK ...
Photorefractive keratectomy (PRK) is an outpatient procedure generally performed with local anesthetic eye drops (as with LASIK/LASEK). It is a type of refractive surgery which reshapes the cornea by removing microscopic amounts of tissue from the corneal stroma, using a computer-controlled beam of light ( excimer laser ).
During the preoperative screening, a complete examination of the eye is carried out at a consultation with the surgeon to determine if a patient is suitable for Laser Blended Vision treatment. The dominant eye is determined and vision tested to identify the level of correction required for distance and near on the dominant eye and non-dominant eye.
Visual acuity with eye chart at Near 15.7 inches (400 mm) and without (sc: Latin sine correctore) correctors (spectacles); Ncc is with (cc: Latin cum correctore) correctors. See Visual_acuity#Legal_definitions
The technology reduces side effects linked with laser procedures like LASIK and SMILE. [1] It was FDA approved in the US in 2016. The method provides measurement of 22,000 points as compared to 200 points provided by wave front-guided LASIK method. The imperfections in the cornea are recorded and then corrected using a laser. [2] [3]
In LASIK, the surgeon performs a 270-degree, 20 mm long incision, while in SMILE the so-called "side cap cut", which is the incision through which the surgeon extracts the lenticule, is usually about 4 mm long. [5] Currently in the US the procedure is only approved for nearsightedness, but is used for hypermetropia too in other countries. [6]
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
