Abstract Details

Purpose:

To investigate immediate and short-term visual recovery in a large cohort of 2093 myopic eyes (with or without astigmatism) treated with SmartSurfACE procedure, a combination of Transepithelial Photo Refractive Keratectomy (PRK) and implemented using the Smart Pulse Technology (acronym SPT, SCHWIND eye-tech solutions GmbH, Kleinostheim, Germany).

Setting:

Laser Refractive Clinic

Methods:

Retrospective case series. Post-operative outcomes evaluated immediately after the surgery (Day 0), at day 1 and 3 months postoperatively, after myopic SmartSurfACE treatment with mean pre-operative spherical equivalent -4.65±2.53D, range (-16.13D to 0D). At each visit standard examinations were performed pre and postoperatively. The analysis evaluated preoperative corrected and uncorrected distance visual acuity (CDVA and UDVA), and postoperative UDVA, monocularly and binocularly, immediately after the surgery, at day 1 and 3 months follow up. Patient were asked if they could read their phones and asked to send text messages immediately after surgery.

Results:

62% eyes achieved monocular UDVA 20/40 or better immediately after the surgery, while 82% patients achieved binocular UDVA 20/32 or better immediately after the surgery. At 3-month postoperatively, monocular UDVA 20/25 or better was achieved in 94% eyes. Treated eyes achieved immediately after the surgery or by the next day mean UDVA 20/41±8. UDVA improved significantly from Day 1 to 3-months follow up (p<0.0001 for both OS and OD); to mean UDVA 20/21±5 (equal to preoperative CDVA 20/21±8). 92% of patients could read their phones and 78% sent text messages.

Conclusions:

Conclusion: Immediate and short-term visual recovery after SmartSurfACE PRK in our large cohort was rapid, providing functional binocular UDVA immediately after the surgery. Almost all patients were able to read their phones within minutes of their surgery. We postulate that is the advanced myopic ablation pattern of the SmartPulse Technology beam that results in a smoother ablation and more rapid recovery.
