iStent – Micro-Invasive Treatment for Glaucoma – Glaukos – Dr. Lewis

Serving Northeast Philadelphia, the Main Line, King of Prussia, Conshohocken, Philadelphia and Phoenixville


VTG_iStent1

iStent has revolutionized the management of cataract patients with mild to moderate glaucoma. The FDA has approved iStent specifically for the treatment of glaucoma at the time of cataract extraction.

iStent | How it Works

“Bypassing the source of resistance and improving the functionality of the conventional outflow system is an ideal approach to managing OAG.”

Glaucoma is normally associated with increased fluid pressure in the eye. The primary cause of elevated intraocular pressure (IOP) in patients with open-angle glaucoma is a blockage of the trabecular meshwork; a sponge-like tissue located near the cornea and iris through which aqueous humor passes to Schlemm’s canal and into the bloodstream.

iStent:

  • Creates a permanent opening in your trabecular meshwork
  • Improves your eye’s natural fluid outflow to safely lower IOP
  • Works continuously to improve the outflow of fluid from your eyes
  • Improves outflow with a single bypass

Some Philadelphia / Bucks County cataract patients are content to continue using their glaucoma medications following cataract surgery. Unfortunately, the cost of drops and co-payments continue to rise. Furthermore glaucoma medications have systemic side effects and after years patients can develop tachyphylaxis (lower effectivity over time) and allergy to these medications. Also, immediate post-operative pressure spikes in cataract patients with glaucoma can have significant unwanted consequences. These factor motivate skilled cataract surgeons to combine cataract surgery with minimally invasive glaucoma surgery (MIGS). Similarly, many cataract and glaucoma patients prefer their surgeon address both conditions at the time of surgery. In certain cases a combined surgical procedure is absolutely necessary to maintain ocular health.

Non-penetrating deep sclerectomy (NPDS) combined with cataract surgery is another excellent choice for patients with cataracts and glaucoma. Alternative procedures like trabeculectomy, mitomycin trabeculectomy, Express Shunt, Ahmed Value, Molteno Tube and other setons significantly delay visual rehabilitation after cataract surgery. Dr. James Lewis has been performing combined cataract and NPDS for almost a decade. In particular, he uses the AquaFlow implant to maintain excellent glaucoma pressure control after cataract surgery. Visual recovering is almost immediate and comfort is maintained. Unlike full thickness glaucoma procedures, no excessive pressure fluctuations, flat chambers, choroidals, choroidals hemorrhages, macular edema or retinal hypotony occur. Cataract extraction and Aquaflow surgery as a combined procedure take less than 30 minutes, is performed under local anesthesia, use no sutures, has no foreign body sensation and does not involve cosmetic abnormalities resulting from removal of iris tissue. (Almost all other glaucoma procedures involve removing small portions of the iris and can distort the size and shape of the pupil.) Dr. Lewis has performed thousands of these procedures and is the most experienced PanOptix surgeon in the United States.

For patients with even more aggressive glaucoma, Dr. Lewis may choose to combine cataract surgery with an Ahmed Valve.  Dr. Lewis began performing glaucoma tubes and valves under the auspices of Doug Coster (Australia) and Tony Molteno (New Zealand) in 1987.  He was the first surgeon in the area to adopt M4, the most advanced Ahmed Valve for glaucoma.

Nearly one out of six patients of cataract age have some form of glaucoma. Sometimes this has not been diagnosed because glaucoma is a silent condition.

The region marked A is the cataract. Excess pressure causing glaucoma is produced at B. Their proximity help explain why cataracts and glaucoma frequently co-exist. Schlemm’s canal is the exit route for excess aqueous humor C and is the focus of the Aquaflow procedure.
In addition to helping cataracts patients with glaucoma, Dr. Lewis is also experienced in treating cataract patients suffering from astigmatism and dry eye. Dr. Lewis is one of the more experienced cataracts surgeons in the United States, and he has been recognized as a foremost Philadelphia multifocal IOL, astigmatism-correcting, and accommodating IOLs provider.

Chorioretinal folds are a known finding following Chorioretinal folds are a known finding following penetrating glaucoma surgery, as in these two cases who underwent Ahmed valve tube shunt placement. Prevalence is estimated between 10-50% of incisional glaucoma surgeries.

Pic 1.) several linear chorioretinal folds throughout the posterior pole. Intraocular pressure was 4mmHg at the time of this photo. The fundus and visual acuity returned to baseline within a week as IOP leveled at 10mmHg.
Pic 2.) Small choroidal folds can be seen distributed temporal to the macula. This image also demonstrates a large hemorrhage consistent with ocular decompression retinopathy.
Pic 3.) shows complete resolution of the choroidal folds and hemorrhage after 4 weeks in patient 2.

Inflammation of the anterior chamber can create fi Inflammation of the anterior chamber can create fibrin plaques that are readily seen within the pupil. The second and third images demonstrate an almost completely occluded pupil with synechia formation. The fourth image demonstrates an ultrasound biomicroscopy image of a patient in angle closure following complete pupil occlusion from fibrin (blue arrow). Aggressive corticosteroid therapy can ‘melt’ the fibrin and cycloplegics can mechanically disrupt it. Nd:YAG laser can also instantly disrupt total occlusion.

Descemet stripping endothelial keratoplasty (DSEK) Descemet stripping endothelial keratoplasty (DSEK) is a corneal transplant procedure that replaces only the innermost cells of the cornea. It is readily combined with cataract surgery to improve refractive outcomes. This is a one day post operative visit of a DSEK showing faint edema and remaining air bubble. The air bubble will typically dissolve over the first 48-72 hours.

Ocular surface disease is a complex state that rep Ocular surface disease is a complex state that represents a poorly performing pre-corneal tear film. It can frustrate many patients and can be challenging for clinicians. No two cases are alike.

In this case, a young patient without evidence of desiccation or inflammation had persistent physical symptoms. Biomicroscopy revealed clear lid margins, no conjunctival injection, and no corneal epitheliopathy. Meibography (imaging the meibomian glands) provides insight into the cause. A previous course of oral medication that acts on sebaceous glands has likely impacted his meibomian glands as well. The gland dropout is easily seen as truncation and atrophy. The final video demonstrates a noninvasive tear-breakup time where the red squares are regions with early loss of tear film stability.

This is an MDALK (maximum depth anterior lamellar keratoplasty) that retains the innermost layer of cells and membrane, but replaces as much diseased tissue as possible.

Corneal infection! This series of images highlight Corneal infection! This series of images highlights a case of pseudomonas aeruginosa microbial keratitis (corneal infection) related to contact lens wear. Keep in mind the cornea is about 0.5 millimeters thick! Not much room to allow an infection to move deeper.
Pic 1. The resultant scar after the infection cleared.
Pic 2. At presentation, the eye is injected (red) with a large central infiltrate (immune response) and necrotic stromal tissue (dying cells). Pic 3. There was extensive inflammation in the anterior chamber including fibrin strands
Pic 4. Note the presence of a hypopyon (accumulation of white blood cells at the bottom of the anterior chamber).
Pic 5. This is two days after initiating treatment with fortified antibiotics. The pupil is intentionally dilated (for comfort) and anterior chamber inflammation is improving. There is a small unrelated fiber present that was subsequently removed.
Pic 6. A closer look at the scar and the shadow it casts. These scars disrupt the vision permanently. Fortunately this patient has achieved good acuity, yet blur, glare and haze can be persistent.
(Sorry for poor photo quality in pictures 2/3/4)

It is important to work quickly to identify the organism responsible for these infections to tailor treatment appropriately. If left untreated infection can spread to devastating results.
