Quick Overview
Infection or inflammation after eye surgery is a serious postoperative complication that can occur in any surgical procedure, including cataract surgery, LASIK, or corneal transplant.
While mild redness or discomfort is normal, symptoms such as pain, discharge, or sudden drop in vision may indicate infection (endophthalmitis) or inflammation (uveitis or keratitis).
Early detection and prompt treatment are critical to preserve vision.
When to Take It Seriously (Risk Level: High)
Any pain, pus-like discharge, or vision deterioration after surgery is an emergency.
Infections can progress rapidly and cause irreversible damage if not treated within hours.
Common Causes
- Bacterial or fungal contamination during or after surgery
- Unsterile handling of eye drops or contact lenses post-surgery
- Poor wound sealing or flap complications
- Immune reaction to surgical materials
- Delayed epithelial healing or suture-related irritation
- Chronic dry eye or diabetes increasing infection risk
Associated Symptoms
- Increasing pain or throbbing in the operated eye
- Redness spreading beyond normal healing zone
- Blurred or decreased vision
- Thick or yellow discharge
- Eyelid swelling or tenderness
- Sensitivity to light (photophobia)
- Floating spots or haze in vision
Possible Conditions
- Postoperative Endophthalmitis (Intraocular Infection)
- Infectious Keratitis (Corneal Infection)
- Anterior Uveitis or Iritis
- Sterile Inflammatory Reaction
- Wound Leak with Secondary Infection
Diagnostic Steps
Your doctor may perform:
- Slit-lamp examination to assess corneal clarity and inflammation
- Fundus examination to check for vitreous involvement
- Culture and sensitivity tests from discharge or aqueous fluid
- Ultrasound (B-scan) if the cornea is opaque
- Visual acuity and intraocular pressure testing
- Response evaluation to empirical antibiotic therapy
Treatment Options
Immediate and aggressive management is essential.
- Topical broad-spectrum antibiotic drops (fortified or combination)
- Intravitreal antibiotics or antifungals for severe infection
- Systemic antibiotics or steroids as indicated
- Anti-inflammatory drops for sterile inflammation
- Surgical intervention (vitrectomy) if infection spreads to the posterior segment
- Frequent follow-ups to monitor response and adjust medication
Early treatment significantly improves recovery and vision outcomes.
Home Care / Self-Care Tips
- Use prescribed postoperative drops exactly as directed
- Wash hands thoroughly before applying drops
- Do not touch or rub the operated eye
- Avoid swimming, makeup, or dusty environments during recovery
- Wear protective glasses to prevent accidental contamination
- Maintain hygiene of drop bottles and avoid sharing medications
- Follow all postoperative appointment schedules
When to See a Doctor
Seek immediate medical attention if you:
- Experience increasing pain or light sensitivity
- Notice thick discharge or crusting
- Have sudden or progressive vision loss
- Observe increased redness or swelling
- Feel the operated eye is “tight,” “heavy,” or unusually watery
Prompt examination can prevent permanent visual loss.
FAQs
Q1: Is some redness normal after surgery?
Yes, mild redness is normal, but increasing redness or discharge is a warning sign.
Q2: How soon can infection occur after surgery?
Usually within a few days, though late infections can appear weeks later.
Q3: Can I prevent infection by using antibiotic drops?
Yes, but only when used as prescribed — overuse or self-medication can worsen outcomes.
Q4: Does pain always mean infection?
No, mild irritation can be normal, but sharp or persistent pain should be evaluated.
Q5: Will vision return to normal after infection?
If treated early, most patients recover well. Delay in treatment can lead to permanent damage.
