Visual and Refractive Outcomes Following SMILE to Correct Myopia Performed by Surgeons in Training

PURPOSE

To assess visual outcomes and complications following small incision lenticule extraction (SMILE) performed by cornea fellows under the supervision of experienced surgeons.

METHODS

This retrospective, noncomparative case series was designed to assess outcomes following SMILE procedures performed at a large surgical center by cornea fellows between May 1, 2012 and March 30, 2015. Preoperative and postoperative uncorrected distance visual acuity (UDVA), preoperative and postoperative corrected distance visual acuity (CDVA), spherical equivalent (SE) up to -10.00 diopters (D), and complications were recorded.

RESULTS

A total of 114 patients (228 eyes) met the inclusion criteria. The mean preoperative SE was -5.79 ± 1.95 D (range: -1.75 to -10.00 D) and the mean cylinder was -2.21 ± 1.43 D (range: 0.00 to -5.50 D). At the last follow-up visit (average: 6.4 months), 94% of the patients achieved a UDVA of 20/30 or better and 96% of the patients achieved stability in their vision. Adverse events were encountered in 40 eyes (17.5%), with epithelial defect being the most common. Two patients required a second intervention to improve visual outcomes.

CONCLUSIONS

SMILE performed by cornea fellows under the supervision of an experienced surgeon is an effective and safe refractive procedure with a short learning curve and excellent visual outcomes. [J Refract Surg. 2022;38(1):28-34.].

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.

Demographics of patients having cataract surgery after laser in situ keratomileusis

PURPOSE

To retrospectively assess the demographics of patients having cataract surgery in eyes with previous laser in situ keratomileusis (LASIK).

SETTING

Department of Ophthalmology, Kitasato University, Kanagawa, and Sanno Hospital, Tokyo, Japan.

DESIGN

Retrospective case series.

METHODS

This study evaluated eyes of consecutive patients scheduled for cataract surgery after previous LASIK (Group 1). The control groups comprised eyes with axial lengths (ALs) matched with ALS in Group 1 (Group 2) and all eyes scheduled for cataract surgery (Group 3). Assessed were age, sex, corrected distance visual acuity, manifest refraction, keratometry (K) readings, corneal astigmatism, and corneal higher-order aberrations (HOAs).

RESULTS

Group 1 comprised 40 eyes of 40 patients; Group 2, 606 eyes of 606 patients; and Group 3, 3642 eyes of 3642 patients. The mean age at cataract surgery of patients in Group 1 was 54.6 years ± 8.1 (SD), which was significantly younger than in Group 2 (by approximately 10 years) and Group 3 (by approximately 15 years) (P < .001, Student t test). In Group 1, 70.0% of patients were men, a significantly higher percentage than in Groups 2 and 3 (P < .05, Fisher exact test). The rate of corneal HOAs was significantly higher in Group 1 than in Groups 2 and 3 (P < .05, Student t test). There were no significant differences in other demographics except in K readings.

CONCLUSION

A long AL and an increase in corneal HOAs might contribute to a tendency for cataract surgery to be performed earlier in eyes in which LASIK has been performed.

Association Between Surgeon Experience and Complication Rates in Adult Scoliosis Surgery: A Review of 5117 Cases From the Scoliosis Research Society Database 2004-2007

STUDY DESIGN

Retrospective review of a multicenter database.

OBJECTIVE

To evaluate whether surgeon experience is associated with complication rates in adult spinal deformity (ASD) surgery.

SUMMARY OF BACKGROUND DATA

Multiple patient- and surgery-related factors have been shown to increase the risk of complications in ASD. No study exists evaluating surgeon experience as an associated factor with complications in ASD.

METHODS

The Scoliosis Research Society Morbidity and Mortality database was queried for patients older than 18 years who underwent ASD from 2004 to 2007. Patient demographics, surgical characteristics, complications, and surgeon membership status were analyzed. Two-tailed t test and χ tests were performed, with P value of less than 0.05 considered significant.

RESULTS

A total of 5117 patients underwent ASD surgery. The average patient age was 51.8 years. Patients operated by candidate members were older than those operated by active members (53.1 vs. 51.4, P = 0.003). Active members performed 3836 (75%) cases whereas candidate members performed 1281 cases. There were 1110 (21.7%) revisions. A total of 681 (13.3%) complications were recorded, 498 (13.0%) for active and 183 (14.3%) for candidate members, respectively (P = 0.24). Mortality rate was 0.29%. Spinal cord complications accounted for 0.68% of all cases. Active members had 21 (0.55%) spinal cord complications, whereas candidates had 14 (1.1%) (P = 0.049). There were a total of 174 (3.4%) surgical site infections (SSI). Active members had 82 (2.1%) deep SSI, whereas candidate members had 36 (2.8%) deep SSI (P = 0.164). Active members had 33 (0.9%) superficial SSI whereas candidate members had 23 (1.8%) superficial SSI (P = 0.008).

CONCLUSION

There was a statistically significant, 2-fold increase in the rate of spinal cord complications and superficial SSI among candidate compared with active members. Overall complication rates were similar between candidate and active members.

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.
