For more than two decades, Lil Jon’s dark sunglasses have been as recognizable as his booming ad-libs. Now, the crunk pioneer has revealed the childhood trauma behind them—a severe injury that ultimately required a corneal transplant.

At age six, Lil Jon accidentally stabbed his eye with one of his mother’s insulin syringes, theGrio reported. He shares the full story in his memoir, I Only Shout So You Can Hear Me, released Oct. 20.

His journey is a sobering reminder of how quickly everyday household items can lead to pediatric trauma. Here is what medical experts want families to know about corneal transplants, long-term recovery, and protecting young eyes at home.

Why does Lil Jon always wear sunglasses?

Lil Jon’s mother, Carrie, lived with diabetes, and he often watched her administer insulin injections. Driven by childhood curiosity, he picked up one of her syringes and accidentally punctured his eyeball. As a result, doctors diagnosed a traumatic cataract.

Over time, the injury required several surgeries, including a transplant of the cornea. Later, he developed a lazy eye and had another operation. In school, he wore a metal eye patch. “I definitely was teased in school,” he said. Still, he turned the pain into motivation. “I used that as fuel in my fire to excel,” he told People.

After that later surgery, the sunglasses stayed. Eventually, they became one of his best-known trademarks.

While Lil Jon has not confirmed whether he experiences chronic photophobia today, eye specialists note that light sensitivity is a frequent long-term reality after reconstructive eye procedures. Jason Edmonds, MD, a board-certified ophthalmologist and cornea specialist at Milwaukee Eye Care, pointed to several possible causes. They include “post operative inflammation present during healing, an increase in dry eye or eye surface health issues, or other eye conditions which may or may not be related to the surgery.”

Raymond Douglas, MD, PhD, a board-certified oculoplastic surgeon in Beverly Hills, pointed to nerve damage. “Corneal nerve damage can cause pain from normal light exposure because nerves send abnormal pain signals,” he told Blavity Health. Those nerves also help make tears. As a result, damage can leave an uneven tear layer that scatters light. If light bothers you, he suggests asking your doctor about lubricating drops and to “consider sunglasses that block ultraviolet (UV) light and wrap around the sides.”

Understanding corneal transplants

The cornea is the clear, dome-shaped front of the eye. “It is the first structure through which light must pass to be focused for vision,” Edmonds told Blavity Health.

A corneal transplant replaces part or all of a damaged cornea with healthy donor tissue, according to Mayo Clinic. Doctors use it for scarring, swelling, thinning, infections that won’t heal and conditions such as keratoconus.

Injuries are one reason. “Cornea injuries can result in scarring or an irregular corneal surface,” Edmonds said. In that case, a transplant may help when glasses or contacts can’t. However, that only works “if the other parts of the eye important for vision are not damaged.”

Not every transplant is the same. According to Mayo Clinic, the main types include:

  • Penetrating keratoplasty (PK), a full-thickness transplant that replaces the entire cornea.
  • DSEK and DMEK, which replace only the back layers of the cornea.
  • DALK, which replaces the front and middle layers while leaving the back layer in place.

In a full-thickness transplant, the surgeon removes a circle of damaged tissue. “Full thickness transplant removes a button of corneal tissue, similar to using a cookie cutter to create a circular shape,” Edmonds said. Next, the surgeon trims donor tissue to match. Finally, “multiple sutures are then passed by hand to secure the donor cornea in the recipient eye.”

Recovery takes patience. “Vision recovery is not instantaneous but rather a long process,” Edmonds said. “Full recovery after a full thickness transplant may take 6 to 12 months or even longer.” During that time, the surgeon may remove stitches during office visits to sharpen vision and prevent problems.

In addition, Douglas said stitches after a full-thickness graft “are often left in place for at least a year.” Steroid eye drops to help prevent rejection typically continue for many months, too.

What a corneal transplant can—and cannot—fix

A new cornea can’t fix everything. For example, a transplant only helps when the rest of the eye can still see. If the injury also damaged the retina or optic nerve, a clear cornea may not restore sight.

Kids face another challenge. Badr Chaban, MD, MRCPCH, MSc, is a UK-based consultant pediatrician and medical director of London Paediatric Clinic. He said an injury can cause amblyopia, or lazy eye. That happens when it blurs vision “during the years when the brain is learning to see.” Then, “the brain may then begin favoring the unaffected eye, and delayed treatment can leave lasting visual impairment,” he told Blavity Health.

Problems can also show up long after the injury. “It is not uncommon for me to see patients years after their eye injury,” Douglas said. For that reason, he said it’s important to follow these patients “for a prolonged period of time after their injury.”

That may explain why Lil Jon needed another operation years after the first injury. Even after a successful transplant, many patients still need glasses or contact lenses for their best vision.

Navigating risks and safety considerations

Like any surgery, this one carries risks. “Some of the risks of corneal transplantation include infections, eye pressure problems, cataract formation and immunological graft rejection,” Edmonds said.

Rejection happens when the immune system attacks the donor tissue. In fact, it occurs in about 10% of cornea transplants, according to Mayo Clinic. Moreover, “graft rejection is a lifetime risk with any transplant,” Edmonds said. The good news is that doctors can often treat it with steroid eye drops or sometimes oral medication.

Because of that risk, know the warning signs. Mayo Clinic lists vision loss, eye pain, red eyes and light sensitivity. If you notice any of them, call your eye doctor right away.

Follow-up care matters, too. Antibiotic drops, a strict post-op routine and regular visits help prevent infection. In addition, Edmonds said stitches “can break or become infected requiring urgent care by your doctor.”

What to Do if Your Child Hurts Their Eye

  • For chemicals: Flush the eye right away with clean, lukewarm water for 15 to 20 minutes, Chaban said.
  • For objects stuck in the eye: Don’t pull them out or press on the eye. Instead, cover it with a rigid shield that doesn’t touch the eye and get emergency care.
  • For any injury: Don’t let your child rub the eye, according to the American Academy of Ophthalmology.
  • Go to the ER for: Severe pain, blurry or lost vision, blood in the eye, an odd-shaped pupil, light sensitivity or trouble opening the eye.

Also, childproof from a toddler’s height. “Look at bedside tables for sewing needles, pins, medication syringes, scissors, loose batteries, and cleaning sprays,” Chaban said. Keep sharps in secure containers right after use, and lock up cleaning products.

Non-surgical treatments and surgical alternatives

Surgery isn’t always the first step. For instance, glasses or contact lenses can correct some vision problems from a scarred or irregular cornea. Edmonds said a transplant comes into play “when vision correction with glasses or contact lenses is not possible due to corneal problems.”

If a donor cornea isn’t an option, an artificial cornea, called a keratoprosthesis, may be, according to Mayo Clinic. Ask your eye doctor which choice fits your eye, and check your coverage options before surgery.

Of course, the best alternative is prevention. More than 90% of eye injuries can be prevented with proper protective eyewear, according to the American Academy of Ophthalmology. For families managing diabetes, that means storing insulin syringes and pen needles out of children’s reach.

Finally, speak up if a doctor brushes off your concerns. Black patients are too often dismissed, and an eye injury needs prompt follow-up even when it looks healed. “Even if a child’s eye looks healed after a penetrating injury, they might be developing cataract, altered eye pressure or reduced visual development without showing any obvious signs,” Chaban said.

Bottom line

Lil Jon’s corneal transplant began with a household accident. Needles, sharp objects and chemicals belong out of kids’ reach. A corneal transplant can restore sight, but recovery can take a year or more, and rejection remains a lifelong risk. If you or your child has an eye injury, get care quickly and keep every follow-up visit.

Frequently Asked Questions

How painful is a corneal transplant?

You shouldn’t feel pain during surgery because you get medicine that numbs the eye or helps you relax, and eye drops ease discomfort afterward, according to Mayo Clinic.

How many cornea transplants can a person have?

A person can have more than one if a graft fails, but each repeat surgery carries a greater risk of failure, Edmonds said.
