A 22-year-old female underwent uneventful femtosecond-assisted laser in situ keratomileusis (Femto LASIK; Intralase, Abbott Medical Optics) in both eyes. Intraoperative epithelial disturbance due to difficult flap lifting was documented in the right eye. One week later, faint interface opacity [Figure 1]a suggestive of Grade 1 epithelial ingrowth (EI) was noted, which organized into inconspicuous pearls at 1 month [Figure 1]b with uncorrected visual acuity (UCVA) of 20/20. Eighteen months later, the patient presented with blurred vision in dim light and a whitish lesion in the right eye. EI had progressed into a thick plaque (3 × 3 mm) [Figure 2]a with UCVA of 20/30 in mesopic light. The patient refused surgical intervention due to the risks involved and chose to follow up closely for progression. Twenty months later (after pregnancy) EI had regressed significantly with faint haze [Figure 2]b and UCVA was 20/20 in both mesopic and bright light.

EI is a rare complication that can occur after primary LASIK or following enhancement procedure. Clinical presentations range from asymptomatic interface changes to severe visual impairment and even flap melt in untreated EI. Indications for conservative/surgical treatment are guided by the patient's symptoms, location/severity of EI, and presence of associated flap dislocation. Rapuano reported that 64% of EI did not require any intervention. According to the Probst/Machat classification, treatment is generally recommended for Grade 2/3 EI (>2 mm from flap edge involving visual axis). However, surgical treatment has its own set of disadvantages such as high recurrence (44%), postoperative folds/irregular astigmatism, and infection.
EI post primary LASIK is usually not progressive, as the implanted epithelial cells during primary flap creation usually have a minimal proliferative ability. These EI might have an initial progressive phase but subsequently regress thereafter. The literature search revealed two other similar reports of spontaneous regression following microkeratome-assisted LASIK., One followed a flap repair that regressed 20 months later and another that progressed at 23 months regressed 6 months later. Hence, we conclude that EIs do not always need an aggressive surgical management. Close follow-up of patients with EI regardless of its grade for a longer period of time is mandatory.
