Hello. I’m Dr. Jinhag Baik, an ophthalmologist and head director of nuneHIM Eye Center on Siheung-daero in Guro-gu, Seoul.
After Korea’s college entrance exam season and toward year-end holidays, many adults ask a practical question—not only “Am I a candidate for laser vision correction?” but “If I have surface ablation, when can I get back to my desk and screens?”
Short answer: Return-to-work timing is not a guaranteed calendar day. It depends on epithelial healing, pain, vision fluctuation, and dry-eye symptoms, and on your job (especially long monitor hours and driving). Marketing lines that promise “back in N days” oversimplify the evidence.
At our clinic, 투데이라섹 (Today LASEK) refers to an all-laser surface-ablation approach in the PRK family (laser for the epithelium through stromal correction), rather than alcohol- or brush-assisted epithelial removal. The recovery numbers below come from general PRK / LASEK / transepithelial PRK (trans-PRK) studies and American Academy of Ophthalmology (AAO) materials—not from a proprietary branded protocol trial. When evidence is for PRK/LASEK generally, I say so.
What is surface ablation?
Laser vision correction reshapes the cornea. Flap procedures (such as LASIK) create a hinged flap; surface ablation removes or ablates the epithelium and treats the stroma from the surface. Names in this family include PRK, LASEK, and transepithelial PRK (TransPRK). AAO EyeWiki describes TransPRK as a PRK variant in which the epithelium is removed with the laser.
After surface ablation, a bandage contact lens (BCL) protects the regenerating epithelium. Until the surface heals, exposed nerves can cause pain, tearing, light sensitivity, and blur—so comfort for work is tied to healing, not only to an eye-chart score.
Typical recovery stages (AAO guidance)
According to AAO EyeWiki on PRK:
| Phase | What patients often notice |
|---|---|
| Day 0–3 | BCL in place; tearing, foreign-body sensation, light sensitivity, blur; discomfort often worst on days 2–3 |
| ~3–4 days | Epithelium grows from the edges toward the center |
| ~Day 4–5 | An epithelial “ridge” often allows BCL removal; vision may be roughly 20/30–20/50, still improving |
| Next 4–6 weeks | Surface smooths; vision gradually clears |
| ~3–6 months | Refraction often considered relatively stable |
EyeWiki notes that after PRK/LASEK, many people can drive and return to work within about 3–6 days, depending on recovery. AAO’s patient page on laser surgery recovery also stresses that PRK takes longer than flap procedures for comfortable return to work and driving because surface cells must regrow over several days.
What studies show about epithelial closure
Hashemi et al., 2022 (randomized contralateral trial, PMID 35148689).
In arm A (39 patients), mean epithelial healing was 3.74 ± 0.82 days after transepithelial PRK versus 3.59 ± 0.79 days after mechanical PRK (P=0.21). In arm B (33 patients), both transepithelial and alcohol-assisted PRK averaged 3.67 days. Safety, efficacy, and haze did not differ significantly. After adjusting for initial defect size, conventional PRK healed faster by rate, and day-1 pain was lower with conventional PRK in that study.
What that number is not: a promise that you can work on day 3, or that “all-laser” always heals a day or two sooner than alcohol-assisted methods.
Duru et al., 2020 (PMID 31495762).
In 43 patients after bilateral PRK, complete re-epithelialization by day 3 occurred in 81.3% of eyes with one silicone-hydrogel BCL and 83.7% with another. Roughly one in five eyes was not fully closed by day 3.
Bakhsh et al., 2018 (PMID 30538854, nonrandomized contralateral).
Complete epithelial healing averaged 3.20 ± 0.686 days after TPRK versus 4.60 ± 1.969 days after alcohol-assisted PRK; early vision and comfort favored TPRK, with similar outcomes at 6 months. Nonrandomized design limits how strongly we can generalize.
Pain control
An AAO Ophthalmic Technology Assessment (Steigleman et al., 2023, PMID 36207168) found better post-PRK pain control with systemic NSAIDs/opioids, topical NSAIDs, cold patches, BCLs (notably senofilcon A in several studies), and topical anesthetics—used as prescribed. Do not replace a dislodged bandage lens yourself; contact the clinic.
Dry eye and vision fluctuation after return
Dry eye and fluctuating vision are common early after both LASIK and PRK.
- Murakami & Manche, 2012 (fellow-eye RCT, PMID 22892151): dry-eye symptoms, fluctuation, and foreign-body sensation rose at 1, 3, and 6 months after both procedures and returned to baseline by 12 months. PRK had more vision fluctuation at month 1.
- Bower et al., 2015 (PMID 26796443): chronic dry eye at 12 months was uncommon—5.0% after PRK and 0.8% after LASIK in that military cohort; lower preoperative Schirmer scores predicted chronic dry eye after PRK.
- Erie et al., 2005 (PMID 16376651): corneal subbasal nerve density recovered near preoperative levels by about 2 years after PRK versus about 5 years after LASIK—an anatomic finding, not a guarantee of fewer dry-eye symptoms.
For office workers in Gasan Digital Complex and Guro Digital Complex, heating, air-conditioning, and long screen hours can magnify early dryness even after the epithelium has closed. Returning to the desk is not the same as tolerating eight hours of fine print.
Practical return-to-work checklist
Decide timing with your surgeon using:
- Epithelial status under the BCL
- Pain you can manage without rubbing
- Stable enough vision for your tasks
- Dry-eye symptoms in your real workspace
- Job demands (all-day monitors, driving, dust, night shifts)
| Activity | Planning tip |
|---|---|
| Light indoor work | After epithelial check and pain improvement |
| All-day monitors | Increase screen time gradually; keep artificial tears available |
| Driving | Separate daytime short trips from night/rain driving |
| Outdoor / dusty work | Treat wind, dust, and UV as extra stress |
| Gym / swimming | Follow clinic infection and trauma guidance; don’t rush water sports |
Who may need a more cautious schedule
Consider extra buffer if you already have significant dry eye or meibomian gland dysfunction, depend on tiny-font screen work or night driving, have high refractive error with a longer expected visual recovery, or have systemic factors that slow wound healing. Suitability still rests on corneal thickness, topography, refractive stability, and the ocular surface—not on a friend’s recovery story.
Bottom line for expats in Seoul
Surface ablation can be an excellent choice when a flap is undesirable, but early recovery is surface-driven. Plan leave around the epithelial check, not around a marketing “day N.” If you work in Guro or Gasan, budget for dry-eye care—lubrication, blink habits, humidity, and a lighter first day back—as carefully as you budget for the surgery date itself.
