The above named service member had __________________________ (type of corneal refractive surgery) performed in the right eye / left eye / both eyes on __________________ (date). As a military or civilian eye care provider (ophthalmologist or optometrist) that has evaluated the service member following his/her surgery, the purpose of this letter is to recommend when he or she may return to work on a full time basis without any further restrictions based on the guidelines provided in paragraphs (2) and (3). I understand this document will be placed in the service member’s outpatient military health record. 2. I understand that most service members are able to resume routine daily work activities within a few days after surgery. However, due to the need for follow-up care in the immediate post-operative time period, service members usually will not be returned to full and unrestricted duty until approximately 1 month following surgical correction of myopia, and possibly as long as 3 to 4 months after surgical correction of hyperopia. Full and unrestricted duty is defined as the ability to perform all job responsibilities of their rank/rate, as well as being suitable for deployment to isolated duty locations where routine eye care services are not readily available. 3. I certify that the following pre-requisites for full and unrestricted duty assignment have been met: a. All topical eye drops (including steroids or anti-inflammatory agents) have been discontinued. Artificial tears may be used as needed. b. Post-operative BEST CORRECTED visual acuity is greater than or equal to 20/20 in each eye that had surgery, OR is within one line of the BEST CORRECTED pre-operative visual acuity in each eye that had surgery: Best corrected visual acuity PRE-OP = Best corrected visual acuity POST-OP = Uncorrected visual acuity POST-OP = c. 20/___ OD, 20/___ OS. 20/___ OD, 20/___ OS. 20/___ OD, 20/___ OS. There are no visually debilitating symptoms related to surgery. 4.

I have reviewed the Medical Clearance Form for Return to Full and Unrestricted Duty Following Corneal Refractive Surgery ICO __________________________________ (Rank/Rate, First name, Last name). 2. As part of the fitness for duty, I have determined if the service member’s job occupation requires a minimum specified visual acuity requirement in order to perform her or his duties (as listed in the Manual of Medical Department). The uncorrected visual results following surgery must meet those specified standards. If the service member’s uncorrected visual acuity following surgery does not meet the specified standards, then the member must have received additional vision correction in the form of glasses or contact lenses that enables him or her to fulfill the visual acuity requirements before returning to duty. 3. In accordance with current BUMED guidance, I have verified that the type of corneal refractive surgery the service member had performed does not disqualify her/him from retention on active duty in his or her current NEC or NOBC. 4a. The service member’s eye care provider (military or civilian) has verified that all of the prerequisites identified in paragraphs 3(a) – 3(c) of the Medical Clearance form have been satisfied. Effective ________________________ (date), the service member may return to full and unrestricted duty, which is defined as the ability to perform all job responsibilities of their rank/rate, as well as being suitable for deployment to isolated duty locations where routine eye care services are not readily available.

Waiver may be recommended if member meets requirements in references, although Study enrollment is no longer required. 2. Caution should be used in selecting surgeons and surgical methods for CRS. Brand names, marketing strategies and technological advances often cause confusion regarding CRS terminology. Photorefractive Keratectomy (PRK) and Laser in-situ keratomileusis (LASIK) are the ONLY Navy approved CRSs. All other forms of CRS including Radial Keratotomy (RK), Laser Thermal Keratoplasty, and Intracorneal Ring (ICR) are PERMANENTLY DISQUALIFYING. 3. Member must have completed all eye medication and be without visual complaints prior to submission. 4. Post-operative refractive stability is demonstrated by comparing two consecutive manifest refractions which must not differ by more than 0.50 D in either sphere or cylinder or both in either eye, and which must be separated by at least one month. 5. The interval after surgery prior to performing final manifest refraction and then submitting this worksheet depends on the preoperative refractive error, as follows: 6. Plano to –5.50 total diopter sphere: three months; 7. -5.75 to –8.00 or +0.25 to +6.00 total diopter sphere: six months. 8. If the initial pair of post-operative manifest refractions does not demonstrate stability, repeat a manifest refraction at one month intervals until they are stable and report only the final two. 9. Note: all SNA candidates require a post-operative cycloplegic refraction recorded on the SF-88. 10. SNA/SNFO accessions must meet all other aviation vision standards; history of CRS does not guarantee selection for nor completion of flight training.
