Vision after PRK can fluctuate during the healing process. It may appear relatively clear soon after surgery, become more blurred the following day, and then gradually improve over the following weeks. Dr. David Robinson has experience guiding patients through PRK recovery and explains that changes in vision during the healing period can be concerning, particularly when patients do not know what to expect. These changes do not necessarily indicate a problem, although significant or unexpected changes should always be discussed with the surgeon.
The First 72 Hours After PRK
This is often one of the more uncomfortable stages of recovery. A bandage contact lens protects the eye while the epithelium, the eye’s outer layer, grows back over the treated area. Grittiness, watering, light sensitivity and blurred vision are common during this early period.
Patients are generally advised to use this time for rest, keep rooms comfortably dim and limit screen time while the corneal surface heals. Dr. David Robinson also advises patients to follow their prescribed medication schedule and postoperative instructions during these first few days.
When the Bandage Contact Lens Is Removed
The bandage contact lens is often removed around days four to seven, once the epithelium has healed sufficiently. Vision may remain hazy at this stage, and some patients notice halos around headlights or lamps in the evening.
Patients should not resume driving until their vision is sufficient for safe driving and their surgeon has confirmed that it is appropriate. The timing can vary depending on how each eye is healing.
During the Second Week
Visual fluctuations may begin to become less noticeable during the second week. Vision may still vary between morning and evening, while overall clarity gradually improves.
Many patients can return to desk work and screen use during this stage, depending on how their eyes are healing. Physically demanding work and activities involving dust or debris may require additional precautions.
Glare around lights may persist and can improve as the corneal surface continues to heal.
Weeks Three and Four
By weeks three and four, many patients notice further improvement in day-to-day vision. Reading, driving and routine screen use may become more comfortable during this period, although some visual symptoms can remain.
Night driving may take longer to become comfortable because of residual halos or glare. Contact sports, swimming and activities that could expose the eye to injury may need to be avoided during this period. The timing for returning to these activities varies, so patients should follow their surgeon’s specific instructions.
One to Three Months After PRK
Visual fluctuations may continue to decrease during this period. Some patients continue a prescribed steroid drop regimen, with the dose reduced according to their surgeon’s instructions.
Dr. David Robinson notes that dry-eye symptoms may persist even after other aspects of recovery have improved, as the corneal nerves continue to recover after surgery. Preservative-free artificial tears may be recommended during this period, depending on the patient’s symptoms and the surgeon’s advice.
When Vision Stabilizes
Vision may continue to stabilize over three to six months, although the timeline varies between patients. Factors such as the original prescription, the condition of the eyes before surgery and the individual healing response can influence how long stabilization takes.
Even after vision has improved considerably, some patients may continue to notice occasional dryness, glare or fluctuations before their vision fully stabilizes.
Factors That May Affect PRK Healing
Certain factors may affect the pace of recovery. Not using prescribed antibiotic or steroid drops as directed can interfere with the intended management of inflammation or infection risk.
Patients should also avoid rubbing their eyes, especially during the early stages of healing, as this can disturb the recovering surface. Activities that expose the eyes to dust, debris or potential injury may also need to be restricted until the surgeon confirms that it is safe to resume them.
Dr. David Robinson also advises patients to protect their eyes from ultraviolet exposure during recovery. Following the recommended postoperative care instructions can help support the healing process.
When to Contact Your Surgeon
A sudden drop in vision, increasing redness, thick discharge or worsening pain should be reported to your surgeon promptly rather than waiting for a scheduled appointment.
Mild halos, dryness and day-to-day fluctuations can occur during the first month. However, symptoms that are worsening rather than improving should be discussed with the surgeon.
Understanding the PRK Recovery Timeline
Understanding the typical stages of PRK recovery can help patients know what changes they may experience during healing. Recovery is gradual, and the experience can differ from one patient to another.
Some changes during PRK recovery can be unexpected or concerning to patients even when they are part of the healing process. New, severe or worsening symptoms should still be reported to the surgeon rather than assumed to be a normal part of recovery
