Residency training in refractive surgery

The evolution of refractive surgery training

PURPOSE OF REVIEW

Although refractive surgery is one of the most commonly performed ophthalmic procedures, there is a relative paucity of literature on residency and fellowship refractive surgery education. The purpose of this article is to review the current state and recent updates to refractive surgery education and to evaluate the safety and visual outcomes of trainee performed refractive procedures.

RECENT FINDINGS

Currently, there is no standard refractive surgery curriculum in the United States apart from required mandatory minimum refractive requirements for residents and fellows. Our survey of residency programs confirms that refractive training is extremely varied, ranging from a dedicated refractive rotation with direct surgical experience to only didactics or observation of procedures. There is a proposed standardized framework for refractive surgery training for the military, which may be a starting point in developing a more comprehensive refractive surgery curriculum in residency education. Multiple studies have reinforced the safety of resident and fellow performed refractive surgery.

SUMMARY

Refractive surgery is an increasingly popular procedure and a more comprehensive refractive education is paramount. Future studies are needed to determine how best to provide the fundamental training and surgical experience for trainees in the fast-changing landscape of refractive surgery.

Ophthalmology Residency in the United States: The Case for a National Curriculum

To identify strategies for effective curriculum development and implementation in United States (US) ophthalmology residency training programs. A literature review was conducted for all English-language PubMed/Medline articles relating to ophthalmology residency education or curriculum/curricula. Despite ACGME-defined program requirements outlining curricular goals for US ophthalmology residency training programs, there is no comprehensive, national curriculum with detailed plans for instruction of necessary topics within the 36-month residency training period. Several articles identify a need for detailed curricula on various topics, propose ideas on how residency programs could create curricula, and explore ways of assessing resident competence. There is a paucity of literature evaluating how ophthalmology residents best learn various ophthalmology topics. We need to develop an intentional, comprehensive, and timely national curriculum for ophthalmology residency programs in the US, with detailed plans on how to meet curricular objectives and consideration of the most effective teaching strategies for different ophthalmology concepts.

Effect of Resident Involvement in Ophthalmic Surgery on Patient Outcomes: A Systematic Review and Meta-analysis

PURPOSE

To determine the effect of resident- vs attending-led surgeries on patient outcomes in ophthalmic surgery.

DESIGN

Systematic review and meta-analysis.

METHODS

Two independent authors searched PubMed, EMBASE, and Cochrane Library from inception to March 2022. Categorical data from studies were pooled to report odds ratio (OR) and 95% CIs. Continuous data were analyzed to yield standardized mean difference (SMD) and 95% CIs. Propensity-matched studies were analyzed separately. Study quality was assessed using the Newcastle-Ottawa Scale.

RESULTS

Twenty-four studies were included in this meta-analysis. Seventeen of the 20 outcomes had no significant differences between the 2 cohorts. Notably, many critical cataract surgery-related outcomes showed no significant differences, including posterior capsular tear, lens fragment retainment, and retinal detachment. Among propensity-scored studies, the resident-led surgeries had longer operative duration (SMD 0.81, 95% CI 0.29, 1.33; 3 studies [260 patients], I² = 74%) and had an increased risk of an unplanned return to the operating room (OR 2.58, 95% CI 1.31, 5.06; 4 studies [342 patients], I² = 0%). Among 2 non-propensity-scored, resident-led surgeries had increased incidence of choroidal detachment or choroidal effusion (OR 2.28, 95% 1.02, 5.09; 2 studies [401 patients], I² = 19%). No significant difference was found for ocular hypotony. Significant heterogeneity existed among propensity-scored studies.

CONCLUSIONS

Resident-led surgeries appear overall safe, effective, and comparable to attending-led surgeries with respect to commonly encountered perioperative complications. Specific differences in outcomes exhibit significant heterogeneity and small sample sizes, and may be of unclear or equivocal clinical significance.

Outcomes of Resident-Performed FS-LASIK for Myopia and Myopic Astigmatism

PURPOSE

To evaluate the outcomes of resident-performed femtosecond laser-assisted in situ keratomileusis (FS-LASIK).

METHODS

Records of 138 eyes of 69 patients treated by residents for myopia or myopic astigmatism between March 2018 and June 2020 were reviewed. All preoperative visits, procedures, and postoperative visits were supervised by attending physicians. Follow-up examinations were performed 1 day and 1 month postoperatively. Complications and enhancements were noted. Outcome measures included postoperative uncorrected distance visual acuity (UDVA), refractive accuracy, and complications.

RESULTS

Eighteen residents performed FS-LASIK on a median of 8 eyes (interquartile range: 1.75). Fifty-nine patients (118 eyes) returned for a 1-month postoperative examination. UDVA was 20/40 or better in 117 eyes (99%) and 20/20 or better in 108 eyes (92%). The mean preoperative spherical equivalent (SE) refractive error was -4.01 ± 1.82 diopters (D) in 138 eyes, decreasing to -0.12 ± 0.35 D at 1 month after surgery in the 102 eyes that were refracted. The SE was ±1.00 D in 100 eyes (98%) and ±0.50 D in 94 eyes (93%). The CDVA change was within one line in 100% of eyes. Intraoperative complications occurred in 5 eyes (3.62%), enhancements were performed in 3 eyes (2.17%), and postoperative complications developed in 3 eyes (2.17%).

CONCLUSIONS

Resident-performed FS-LASIK is relatively safe and effective in comparison to published U.S. Food and Drug Administration premarket approval studies. Early resident experience performing LASIK can improve the training of ophthalmic surgeons while simultaneously increasing patient access to laser vision correction.

Femto-LASIK outcomes obtained by a fellowship trainee during a refractive surgery training program

PURPOSE

To report, for the first time, the clinical outcomes and patient satisfaction of laser refractive surgery performed by a trainee during a corneal and refractive surgery fellowship program in Latin America.

METHODS

This prospective and interventionist study reviewed the clinical charts of the first 100 consecutive refractive surgery cases performed by a single Cornea Fellowship trainee between March 2018 and June 2018 in the Blindness Prevention Association of Mexico (Asociación para Evitar la Ceguera en Mexico). Femtosecond LASIK was performed in all eyes. Visual and refractive outcomes were evaluated during the first year of follow-up. Patient satisfaction was measured using 5 author-created questions 6 months after surgery.

RESULTS

Data of 100 eyes of 50 consecutive patients were evaluated. One year after the surgery, mean uncorrected distance visual acuity (UDVA) was 0.01 logMAR. Spherical equivalent error passed from -3.91 ± 2.28 D preoperatively to -0.22 ± 0.28 D. No eyes lost lines in corrected distance visual acuity (CDVA). Manifest refraction maintained stable during the first year after surgery. The five author-created questions revealed a high level of confidence and patient satisfaction.

CONCLUSIONS

Femto-LASIK performed by a corneal and refractive surgery fellowship trainee showed good refractive and visual outcomes, as well as high patient satisfaction and confidence in a refractive surgery centre in Latin America.

Assessment of Factors Associated With Postoperative Pain After Photorefractive Keratectomy

PURPOSE

To define the factors that affect patient's self-assessed postoperative pain after photorefractive keratectomy (PRK).

METHODS

Patients who underwent PRK in 2016 were evaluated. Anonymized data collected included patient gender, age, and season at the time of surgery, ablation depth, surgeon status (attending vs. resident), topical tetracaine use, and subjective pain scores at postoperative days (PODs) 1 and 7. Average pain scores and amount of pain medication taken were analyzed for each of the previously mentioned variables.

RESULTS

Overall, 231 patients who underwent PRK were analyzed. The mean pain score and SD were 0.78 ± 1.87 on POD 1 and 0.03 ± 0.37 by POD 7. Patients who used topical tetracaine reported significantly higher pain on POD 1 and 7 compared with patients who did not use tetracaine (P < 0.001 and P = 0.038, respectively). No significant differences in pain scores were seen based on surgeon status, ablation depth, gender, and season. Patients who used topical tetracaine took a higher amount of oral pain medication (9.44 ± 6.01) compared with those who did not (7.02 ± 4.71) (P = 0.022).

CONCLUSIONS

Postoperative pain was significantly elevated in patients who used tetracaine on POD 1 and POD 7. These patients were also more likely to take oral pain medication than those who did not use topical tetracaine. Surgeon status, season, gender, and ablation depth showed no significant differences in subjective pain scores. Oral pain medication should be evaluated to assess efficacy and safety in inhibiting ocular pain after PRK.

Refractive surgery training during residency - do not be afraid of the dark

Refractive errors are a fairly common eye condition worldwide, and the ophthalmologist should be capable of offering the patient both nonsurgical and surgical solutions to their refractive conditions. Nevertheless, currently, refractive surgery training during residency is poor at best. This paper explores recent evidence to suggest that postsurgical results of patients operated on by residents are not inferior to those operated on by experienced staff. It points out the urgent need to improve the current approach to refractive surgery training.
