Triple DMEK combines three procedures in one operation: a Descemet Membrane Endothelial Keratoplasty (DMEK) to replace the diseased inner layer of the cornea, removal of the cataract by phacoemulsification, and implantation of an intraocular lens (IOL). It is the gold-standard treatment for patients who have Fuchs endothelial dystrophy together with a cataract. At our partner clinics, combined triple DMEK starts from £8,500 per eye, all-inclusive of donor graft tissue, surgery, theatre and aftercare. Most patients are treated as a day case under local or general anaesthetic.
What is triple DMEK?
The cornea is the clear dome at the front of the eye. Its innermost layer — the endothelium — is a single sheet of cells that constantly pumps fluid out of the cornea to keep it transparent. In Fuchs endothelial dystrophy these cells gradually die off, the cornea swells and clouds, and vision becomes hazy, especially first thing in the morning.
DMEK (Descemet Membrane Endothelial Keratoplasty) replaces only that failing inner layer with an ultra-thin sheet of healthy donor endothelium, leaving the rest of your cornea untouched. Because Fuchs and cataract both develop with age, many patients have both at the same time — and because the cataract operation can itself stress an already weak endothelium, surgeons routinely combine the two. Doing the graft, the cataract and the lens implant together — the “triple procedure” — means a single anaesthetic, a single recovery, and the best chance of a clear, well-focused eye.
Who is triple DMEK for?
- Fuchs dystrophy with a visually significant cataract — the most common indication
- Corneal swelling that worsens after cataract surgery is planned — combining avoids a second graft operation later
- Morning blur and glare from a cloudy, water-logged cornea
- Reduced contrast and halos around lights affecting night driving
- Patients wanting one operation and one recovery rather than staged surgery
Have Fuchs dystrophy and a cataract? A consultant corneal assessment with specular microscopy and a pachymetry scan confirms whether a combined triple procedure is right for you.
Book a corneal assessmentCombined vs staged — and graft alternatives
Your consultant will recommend the approach that protects your cornea while giving the sharpest vision. The main routes are:
DMEK gives the thinnest graft and the fastest, sharpest visual recovery of the endothelial techniques. Where DMEK is not suitable, ultra-thin DSAEK is an excellent alternative, and in carefully selected early Fuchs cases Descemet stripping only (DSO) can clear the cornea without donor tissue. Your surgeon will explain which technique fits your eye.
What happens during triple DMEK surgery
The combined operation takes around 45 to 75 minutes and is usually performed as a day case under local anaesthetic, with sedation or general anaesthetic available if preferred.
- The eye is numbed and the cataract is removed first by phacoemulsification through a tiny self-sealing incision.
- Your chosen intraocular lens (IOL) is implanted into the lens capsule, correcting your focus.
- The diseased Descemet membrane and endothelium are gently stripped from the back of your cornea.
- The wafer-thin donor graft — a single layer of healthy endothelial cells — is inserted, unrolled and positioned against the inner cornea.
- A gas or air bubble is placed in the eye to press the graft into position while it bonds. You then rest face-up to keep the bubble in place.

Recovery week-by-week
Corneal grafts clear more gradually than a simple cataract operation. Vision improves over weeks as the new cells start pumping the cornea clear. Here is the typical course:
Day of surgery
A gas bubble supports the graft. You lie flat, face-up, as much as possible for the first 24–48 hours. Vision is very blurred at this stage — this is expected.
Days 1–7
First review to confirm the graft is attached. The bubble shrinks and absorbs over several days. Frequent steroid drops begin to protect the graft.
Weeks 2–6
The cornea steadily deturgesces (clears) as the new endothelium pumps out fluid. Vision improves noticeably week on week.
Months 1–3
Cornea becomes fully transparent in most patients. A new glasses prescription is finalised once vision is stable.
Long term
Low-dose steroid drops continue long term to reduce rejection risk. Graft survival at five years is high with good follow-up.
