About Retained Lens Fragments
Retained lens fragments (RLF) can occur in up to one percent of patients who undergo cataract surgery. They are pieces of the cataract lens that remain in the eye following surgery.
"Five Stars - My husband and I have been Dr Kim’s patient for over 17 years. She is a compassionate, knowledgeable, detailed oriented doctor with excellent bedside manner.

"For the last three years I've been treated by the Retina Consultants of Houston at the Sugar Land location and have been extremely satisfied with the very professional, courteous staff and Dr. Chen. When at the office in the waiting rooms I've spoken with numerous other patients who have all had the same comments of satisfaction. My observations have always been that the staff and doctors work hard to keep patients waiting time at a minimum, while maintaining the excellent quality of care. I would not go any where else."- S.R. / Google / Jun 22, 2018
"Dr. Brown is an excellent surgeon. If you want the best, you have to make a sacrifice. I have been a patient of Dr. Brown, for decades, and I would recommend him to anyone. I would be completely blind if not for Dr. Brown, and God, the Most Holy of Holy."- M.S. / Healthgrades / May 16, 2018
"My left retina had tear in it and I had no clue of what was happening, but was referred to the Retina Consultants of Houston and was blessed with meeting Dr. Wykoff. He repaired my eye while explaining everything in detail and helping me to feel comfortable. Less than a year later my right eye did the same thing but a little worse. Nowadays, I will only let Dr. Wykoff work on me. I am seeing great today and at 58 have zero floaters, etc. This Doctor is the best."- C.P. / Google / Mar 16, 2018

Causes and Symptoms
There are many reasons why patients may be predisposed to retained lens fragments. Sometimes the cataract is very advanced and hard to remove in its entirety. In other cases, the “bag” that the cataract rests in or the zonules that hold it in place can become damaged, and some pieces of the cataract lens can then float into the back of the eye.
Depending on the size and the type of the fragments, patients may experience various degrees of intraocular inflammation, corneal edema, intraocular pressure increase, macular edema, vitreous hemorrhage, or retinal tears or detachment.
Plan Your Procedure
Our physicians at Retina Consultants of Houston specialize in managing and treating retained lens fragments. Your treatment will depend on your specific case and could include:
- Observation: In many cases, the fragments are small enough that they dissolve over time on their own. Our retina specialists may just observe these types of cases closely and monitor or treat any inflammation, intraocular pressure increase, or macular edema.
- Medical Treatment: Inflammation may be treated with anti-inflammatory eye drops. Intraocular pressure can be managed with anti-inflammatory and glaucoma drops. Macular edema can be treated with anti-inflammatory eye drops or with steroid injections around or into the eye.
- Surgical Treatment: If the retained lens fragments are large or dense and/or the inflammation, intraocular pressure, and edema cannot be controlled medically, then surgical intervention may be necessary. A pars plana vitrectomy and lensectomy can be done to remove the residual lens fragments and usually leads to improved inflammation and intraocular pressure. In some cases, medical therapy in the form of anti-inflammatory drops or injections may need to be continued even after surgery to address macular edema.
