One of the most popular and effective refractive eye surgeries is Laser-Assisted In Situ Keratomileusis (LASIK).
It helps correct vision problems such as Myopia, Hyperopia or Hypermetropia, and Astigmatism.
Diffuse Lamellar Keratitis (DLK) is an eye condition that can affect individuals who have undergone LASIK eye surgery.
This article aims to provide comprehensive information about Diffuse Lamellar Keratitis, its symptoms, stages, and more.
Diffuse Lamellar Keratitis: An Overview
Diffuse Lamellar Keratitis is also known as Sands of Sahara Syndrome.
When someone has DLK, there is inflammation in the corneal tissue, especially at the the lamellar interface region.
This region is where the corneal flap was made during LASIK surgery.
It is a postoperative complication associated with LASIK surgery.
While DLK can be a concerning eye condition, most cases respond well to treatment when detected early.
Diffuse Lamellar Keratitis Symptoms

The following are common symptoms associated with Diffuse Lamellar Keratitis:
- Pain and discomfort
- Red Eyes
- Blurry vision
- Excessive tearing
- Sensitivity to light (Photophobia)
- Foreign body sensation
It is essential to consult with an ophthalmologist or eye specialist if you experience these symptoms following LASIK surgery.

Stages of Diffuse Lamellar Keratitis
Diffuse Lamellar Keratitis typically progresses through several stages like mild, moderate, severe, etc.
Understanding these stages is vital for both patients and healthcare professionals. The stages of DLK include:
- Stage 1 (Mild DLK): In this initial stage, the inflammation is relatively mild and often asymptomatic. It may be detected during a routine postoperative visit
- Stage 2 (Moderate DLK): As DLK progresses, the inflammation becomes more pronounced, and patients may experience symptoms such as discomfort, blurry vision, and light sensitivity
- Stage 3 (Severe DLK): This is the advanced stage of DLK, where inflammation is severe and vision can be significantly affected. Severe DLK may lead to corneal scarring if left untreated
- Stage 4 (End-Stage DLK): DLK has reached a critical point in this stage. The corneal flap may be compromised, and patients may experience severe pain and vision loss. Immediate intervention is essential to prevent permanent damage
It’s important to note that DLK can progress rapidly, and early intervention is crucial to prevent the condition from worsening.
Regular ophthalmologist visits are needed to track healing and detect DLK early.
Diffuse Lamellar Keratitis Treatment

The common approaches to treating Diffuse Lamellar Keratitis include eye drops, oral medications, etc.
- Topical steroid eye drops: In most cases, DLK is treated with topical steroid eye drops to reduce inflammation. The eye care professional will determine the type and frequency of steroid eye drops based on the severity of DLK
- Increased monitoring: Patients with DLK, especially in the early stages, may require frequent follow-up appointments to monitor their progress and adjust their treatment
- Oral medications: In severe cases of DLK, oral steroids or anti-inflammatory medications may be prescribed to control inflammation
- Flap lift and irrigation: In rare cases where DLK progresses to a severe stage and poses a risk to the corneal flap, the surgeon may need to lift the flap and rinse the affected area to remove inflammatory cells
- Additional procedures: In rare cases, additional procedures such as amniotic membrane transplantation or corneal grafting may be necessary to address severe complications and corneal scarring
Conclusion
Diffuse Lamellar Keratitis, though rare, is an important consideration for anyone undergoing LASIK surgery.
Symptoms of DLK include eye pain, redness, blurry vision, excess tearing, and increased senstivity to light.
DLK has four stages ranging from mild to end-stage DLK, which can lead to permanent vision loss.
Consult your ophthalmologist if you experience any symptoms of DLK or have concerns about your post-LASIK recovery.
It is essential to follow postoperative care instructions diligently and attend all follow-up appointments with your surgeon.
An early intervention can make a significant difference in managing Diffuse Lamellar Keratitis.
Frequently Asked Questions
How long does it take for DLK to resolve?
The resolution time for DLK can vary depending on its stage and severity. It may resolve relatively quickly in mild cases (Stage 1) with appropriate treatment. However, in more advanced stages, it may take longer. Immediate diagnosis and treatment are essential for a faster recovery.
Is DLK curable?
Yes, DLK is curable, especially when detected in its early stages. Treatment options typically include topical steroid eye drops, increased monitoring, and, in some cases, oral medications. Severe cases may require more intensive interventions.
Is DLK serious?
Yes, DLK can be a serious postoperative complication of LASIK surgery, especially if left untreated or if it progresses to advanced stages. Severe DLK has the potential to cause vision impairment and, in extreme cases, may lead to permanent damage or complications.
How common is DLK?
DLK is a relatively rare condition, but it is an important consideration for individuals undergoing LASIK surgery. While most LASIK procedures proceed without complications, a small percentage of cases may report DLK. Early detection and proper management can minimize the impact of DLK.
Can DLK be prevented altogether?
No, DLK cannot always be completely prevented, as it is a potential postoperative complication of LASIK surgery. However, the risk of DLK can be significantly reduced by strictly following the postoperative care instructions provided by your surgeon.
