Official Description

Corneal relaxing incision for correction of surgically induced astigmatism

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Corneal relaxing incision for correction of surgically induced astigmatism, identified by CPT® Code 65772, is a surgical procedure aimed at addressing astigmatism that has developed as a result of previous eye surgeries, such as cataract removal or refractive procedures like LASIK. Astigmatism is a common refractive error that occurs when the cornea, which is normally round, takes on an oval shape. This irregularity in the corneal curvature leads to blurred or distorted vision. The procedure involves creating small incisions in the peripheral cornea, known as peripheral corneal relaxing incisions (PCRI) or limbal relaxing incisions (LRI), which help to reshape the cornea back to a more spherical form. By doing so, the procedure aims to improve visual acuity and reduce the degree of astigmatism. The surgical technique requires careful mapping of the cornea, precise incision placement, and the use of topical anesthetics to ensure patient comfort during the procedure. Overall, this intervention is designed to enhance the quality of vision for patients experiencing surgically induced astigmatism.

1. Indications

Corneal relaxing incision for correction of surgically induced astigmatism is indicated for patients who exhibit the following conditions:

  • Surgically Induced Astigmatism - This condition may arise following cataract surgery or refractive procedures such as LASIK, where the cornea's shape has been altered, leading to blurred vision.
  • Low Degree of Astigmatism - The procedure is particularly suitable for patients with a low degree of astigmatism, where peripheral corneal relaxing incisions (PCRI) or limbal relaxing incisions (LRI) can effectively restore a more natural corneal shape.

2. Procedure

The procedure for corneal relaxing incision involves several critical steps to ensure its effectiveness and safety:

  • Step 1: Eye Mapping - The first step involves mapping the cornea using a slit lamp. This allows the surgeon to identify the areas that require correction and to place precise markings on the cornea.
  • Step 2: Patient Positioning - The patient is positioned in a supine (lying down) position to facilitate access to the eye during the procedure.
  • Step 3: Eye Preparation - The eye is prepared and draped to maintain a sterile environment. This is crucial to prevent any potential infections during the surgery.
  • Step 4: Anesthesia Application - A topical anesthetic is applied to the cornea to ensure that the patient remains comfortable and pain-free throughout the procedure.
  • Step 5: Corneal Irrigation - The cornea is irrigated with saline to cleanse the area, and a viscolubricant eye solution may be instilled to provide additional lubrication.
  • Step 6: Securing the Globe - The globe of the eye is secured using a suction device or forceps to stabilize it during the incision process.
  • Step 7: Incision Creation - A diamond knife is utilized to make small incisions in the previously marked areas around the axis of the cornea. These incisions are designed to allow the cornea to relax and reshape into a more spherical configuration.
  • Step 8: Post-Procedure Care - At the conclusion of the procedure, a corneal contact lens bandage may be placed on the eye, antibiotic eye drops are instilled to prevent infection, and the eye is patched to protect it during the initial recovery phase.

3. Post-Procedure

After the corneal relaxing incision procedure, patients can expect a recovery period that may involve some discomfort or mild irritation. The application of a corneal contact lens bandage helps to protect the eye and promote healing. Patients are typically advised to use antibiotic eye drops as prescribed to minimize the risk of infection. Follow-up appointments are essential to monitor the healing process and assess the improvement in vision. It is important for patients to adhere to post-operative care instructions and report any unusual symptoms to their healthcare provider promptly.

59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
55 Postoperative management only: when 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 to the usual procedure number.
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
