Conjunctivochalasis (CCh) represents one of the most common age-related eye diseases and is characterized by the presence of redundant folds of the conjunctiva that typically are detected between the eyeball and the eyelids. It is commonly found along the lower lid margin and mechanically interferes with the normal distribution of tears giving rise to unstable tear film (dry eye) and delayed tear clearance (epiphora). The differences between CCh-induced dry eye and aqueous tear deficiency (ATD) are summarized in Table 1. For asymptomatic CCh, no treatment is needed, and patients may be given tear substitutes, lubricants, corticosteroids or antihistamine drops. Persistent symptomatic CCh despite maximal medical treatments to dry eye can be treated using amniotic membrane (AM) transplantation.

The loose conjunctiva can be demonstrated as follows:
Supplies for Conjunctivochalasis Surgery
AmnioGraft® from Bio-Tissue (1-888-296-8858):
Traction Sutures: use 7-0 Vicryl sutures.
For sutureless surgery: use fibrin glue; TISSEEL from Baxter Biologics (1-877-TISSEEL) 2.0 mL (Catalog # 1501236) or Evicel from Ethicon from Johnson & Johnson (1-800-255-2500) 1 mL (NDC # 63713-390-11).
For surgery with sutures, 10-0 nylon and 7-0 Vicryl sutures are recommended.
Surgical Techniques for Inferior Conjunctivochalasis
Conjunctivochalasis with Pinguecula
Remove any pinguecula during the surgery to avoid progression into a pseudopterygium. AM should cover the entire denuded area (Figure 8).
Conjunctivochalasis with Fat Prolapse
(Fig. 9A)Anchor the recessed remaining conjunctival tissue to the fornix using 7-0 Vicryl mattress sutures to the sclera (Fig. 9B).
Pterygium Post-Operative Care
Create a limbal based conjunctival flap about 5 mm posterior to the superior limbus. Rotate the eye down using a 7-0 traction suture 1-2 mm posterior to limbus at the 12 o’clock position. Remove all mobile Tenon’s capsule (Fig. 10A) prior to laying down and adhering AM on the bare sclera with fibrin glue (Fig. 10B). Remove the traction suture and secure the conjunctival flap on top of AM with bipolar cautery.
Post Operative Care
Begin topical Prednisolone four times and Ocuflox three times a day for 4 weeks. Epithelialization will be completed in 2 to 3 weeks. If the surrounding conjunctiva is not inflamed, stop Ocuflox and taper off PF on a weekly schedule from four times a day. If, however, the surrounding conjunctiva is inflamed, give subconjunctival injection of 0.1 cc Kenalog (40 mg/ml) per site in the office. Symptoms related to CCh will be quickly resolved. The residual symptoms due to aqueous tear deficiency, meibomian gland dysfunction (MGD), or excessive blinking can be managed accordingly.
Frequently Asked Questions
Why not just remove the excess conjunctiva? Why use an amnion graft?
CCh is not caused by excessive or redundant conjunctiva. Instead it is caused by poor adhesion between the Tenon’s capsule and the sclera. Simple excision may not prevent fat prolapse and may aggravate a pinguecula, if present. Covering the bare sclera with cryopreserved amniotic membrane reinforces such adhesion without stirring up unnecessary inflammation or scarring based on the important biologic actions preserved in cryopreserved amnion grafts. These include anti-inflammation, anti-scarring, anti-angiogenesis and the promotion of healing while reducing patient pain.
Why are cryopreserved amnion grafts recommended over other amniotic membrane products?
AmnioGraft® is the only cryopreserved amnion graft available and approved by the FDA for commercial use in the United States. The cryopreserved method of preserving amniotic membrane is the only method for use in ocular surface wound repair and wound healing because this method retains the biologic actions of the tissue in utero (anti-scarring, anti-inflammation, anti-angiogenesis, and promotion of healing).
What happens if ocular irritation persists after CCH surgery?
If the conjunctivochalasis has been corrected, the remaining irritation might come from aqueous tear deficiency dry eye, MGD blepharitis, or delayed tear clearance, which can then be successfully treated by punctal occlusion, lid scrub, or non-preserved steroid drops.
Should CCh correction surgery be performed before blepharoplasty?
Yes. If an eye had CCh and the lid is tightened through blepharoplasty, then the symptoms will get worse.
If the patient has entropion with CCh, should both corrective surgeries be performed at the same time?
Operate on the entropion first to see if CCh persists. If so, then CCh will be managed accordingly.
Can this procedure be performed on both eyes in the same surgical session?
Yes, because topical anesthesia makes it possible
