Surgery and Care for In-turned Eyelashes

The “S” in the SAFE strategy stands for Surgery, which is the only definitive way to correct trachomatous trichiasis (TT)—the stage where scarring has pulled the eyelid inward so that the eyelashes scratch the eyeball ^[1].

While antibiotics can kill the bacteria in a community, they cannot fix the physical deformity of a scarred eyelid. Without surgery, the constant scratching of the lashes will eventually lead to permanent blindness ^[2].

Recognizing Warning Signs and Seeking Care

Trichiasis can progress quickly and cause irreversible damage. Triage is important:

• Prompt Care Needed: Any inward-turning eyelash that touches the surface of the eye requires a prompt clinical assessment. Do not wait for a community antibiotic campaign; antibiotics will not fix the eyelashes ^[1].
• Urgent Care Needed: Seek evaluation immediately if you experience severe eye pain, sudden worsening of vision, extreme light sensitivity, or a new dense white spot on the cornea. These are red flags for serious damage to the eye’s surface ^[3][2].

How Eyelid Rotation Surgery Works

The goal of surgery is to “rotate” the edge of the eyelid outward so the lashes no longer touch the eye ^[4]. This is a procedure usually performed under local anesthesia, meaning you are awake but the eye area is completely numb.

Two common surgical methods include PLTR (Posterior Lamellar Tarsal Rotation) and BLTR (Bilamellar Tarsal Rotation) ^[4]. Both involve making a small incision to correct the angle of the lid and can be performed by ophthalmologists or specially trained ophthalmic assistants ^[5]. Some studies suggest the PLTR method may have a lower risk of the lashes turning back in later ^[6][7], while BLTR is also a very common method and is highly effective when performed by trained providers ^[8].

Important: Eyelid surgery prevents further lash trauma, but it generally cannot reverse established corneal scarring or restore vision that has already been lost. This makes early intervention essential.

What to Expect During Recovery

Post-operative care varies by local program, but you will often have your eye covered with a patch for a short time (usually one day) and may receive specific eye ointments or pain relief ^[9]. Mild swelling or bruising is common.

• Follow-up Visits: You will typically need to return to the clinic the day after surgery, and again at specific intervals (like two weeks and six months) to ensure the eyelid is healing ^[9][10].
• Post-Operative Red Flags: Return to the clinic immediately if you experience worsening pain, heavy discharge, severe swelling, or new vision loss after surgery.
• Recurrence Risk: While surgery is very successful at relieving pain and protecting vision ^[11], it is not a permanent guarantee for everyone. Depending on the severity of the scarring, between 10% and 40% of people may experience recurrence, where the lashes begin to turn inward again within a few years ^[12]. If this happens, repeat assessment and potentially a second surgery are necessary ^[13].

Epilation: A Temporary Measure

Epilation, or plucking the eyelashes with forceps, is sometimes used as a temporary bridge while awaiting surgery ^[14].

• Safety Warning: Unclean or forceful self-plucking at home can cause corneal injury, infection, or additional damage ^[15]. Epilation should only be performed or demonstrated by a trained provider using clean instruments.
• It is not a cure: The eyelashes commonly grow back within a few weeks and will continue to scratch the eye, meaning the risk of blindness remains ^[16].
• When it is used: Epilation is a temporary measure for minor trichiasis (very few lashes) if surgery is delayed or declined ^[14]. Any lash touching the eye still requires definitive surgical assessment to protect long-term vision ^[5].
