MIGS glaucoma surgery in Frisco starts with a pressure plan.
A glaucoma diagnosis can feel overwhelming — especially when you're managing drops that sting, blur your vision, and never seem to end. Frisco patients drive 15 minutes south to Plano because Dr. Shehz builds a pressure-lowering plan around your nerve, your angle, and your life — not just the next refill.
You were told you have glaucoma. Now you need a surgeon who explains the plan.
Glaucoma is irreversible. The nerve fiber you lose today does not come back, which is why an elevated pressure reading, optic nerve thinning, or a new visual field defect turns the question from convenience to expertise almost immediately.
Dr. Shehz is double board-certified, completed his ophthalmology residency at Dean McGee Eye Institute, and has performed nearly 7,000 procedures including MIGS combined with cataract surgery. He reviews your OCT scans, visual fields, pressure history, and gonioscopy before recommending a device — iStent, Hydrus, goniotomy, canaloplasty, Durysta, or iDose. If your disease is too advanced for MIGS, he says so plainly and discusses whether trabeculectomy, a tube shunt, or referral to a glaucoma sub-specialist is safer.
Many Frisco patients arrive already on two or three bottles of drops, some after years of being told to keep using them without a clear discussion of the alternatives. Others are newly diagnosed and buried in jargon. The consultation runs about 90 minutes because we repeat the imaging in-house, and if MIGS and cataract surgery are both appropriate they can often be done in one session — fewer trips, less anesthesia. Records transfer from your Frisco provider is handled by our team.
A target pressure your nerve can actually tolerate. Not a number copied from a textbook.
i.
One surgeon, full accountability.
The physician who reads your OCT and fields is the one who operates and follows your pressure afterward. No handoff, no rotation, no meeting the surgeon on the day of the procedure.
ii.
Pressure goal before device choice.
The device is never chosen first. Your target IOP is set based on nerve damage, progression rate, and life expectancy — then the device that best reaches that goal is discussed.
iii.
Honest about MIGS limits.
If your glaucoma is too advanced for a micro-invasive approach, you'll hear it clearly — along with the next step, whether that's traditional surgery or a sub-specialist referral.
02/Understanding your options
Understanding your glaucoma treatment options.
Glaucoma is not a single disease — it is a family of optic neuropathies where elevated or fluctuating intraocular pressure damages the optic nerve over time, gradually narrowing the visual field. Because peripheral vision disappears first and painlessly, most patients don't notice the loss until it's significant. That's why glaucoma is called the 'silent thief of sight,' and why a proactive treatment plan matters more than waiting for symptoms.
Traditional management starts with prescription eye drops — one, two, sometimes three or four bottles a day. Drops work for many patients, but compliance is imperfect, side effects accumulate, and the daily burden grinds. Selective laser trabeculoplasty (SLT) offers a drop-free alternative for some, while advanced disease may require filtration surgery such as trabeculectomy or tube shunt. Between drops and traditional surgery sits MIGS: minimally invasive glaucoma surgery.
MIGS procedures — iStent, Hydrus, goniotomy, canaloplasty, Durysta, and iDose — use tiny devices or micro-incisions to lower pressure with less tissue disruption than traditional surgery, often at the same time as cataract removal. They don't replace traditional surgery for advanced glaucoma, but for mild-to-moderate disease they can meaningfully reduce drop burden, stabilize pressure, and protect remaining nerve fiber. The right device depends on your angle anatomy, pressure history, optic nerve status, and whether cataract surgery is already in the plan.
03/MIGS device options
Micro-invasive procedures matched to your pressure goals.
Which device fits depends on your pressure readings, nerve health, drop burden, and whether cataract surgery is part of the plan. Dr. Shehz walks through each option with you at consultation.
Trabecular micro-bypass stent
iStent
One of the smallest medical devices ever made, iStent is placed during cataract surgery to create a permanent opening in the trabecular meshwork, improving the natural outflow of aqueous humor and reducing intraocular pressure for mild-to-moderate open-angle glaucoma.
Hydrus is a flexible, crescent-shaped micro-stent that scaffolds open a large section of Schlemm's canal — the eye's natural drainage channel — during cataract surgery, providing a broader pressure-lowering effect than a single-point bypass.
Goniotomy removes a strip of diseased trabecular meshwork to restore direct drainage into Schlemm's canal. No implant is left behind, and it can be performed alone or combined with cataract surgery depending on the clinical picture.
Canaloplasty dilates and opens the full 360 degrees of Schlemm's canal using a microcatheter, restoring the eye's natural outflow system without leaving a permanent implant. It may suit patients whose angle anatomy supports a canal-based approach.
Durysta is a biodegradable implant placed inside the eye that slowly releases bimatoprost over months, reducing pressure without the burden of daily drop administration. It is a medication-delivery option, not a drainage device.
iDose TR is a tiny titanium implant placed inside the eye that continuously delivers travoprost directly to the trabecular meshwork, offering sustained pressure control and reducing or eliminating daily drop use for appropriate patients.

Dr. Shez is the most informative and detail oriented LASIK doctor I have met in my entire life. With other LASIK doctors, the volume of patients they have is so high that they don't take the time to discuss with you what your options are. Dr. Shez on the other hand took over an hour the first time I visited and made sure to explain to me the variety of… Read full review

I had a great experience with Visionary Eye Surgery and Dr. Shehz throughout my LASIK journey. From the consultation to the follow-ups, the staff was professional, patient, and reassuring every step of the way.
Even when I had a healing complication with one eye early on, they took care of it immediately, stayed in close contact with me, and made sure I… Read full review

05/Getting here
The drive is the easy part.
The route
Dallas North Tollway or Sam Rayburn Tollway south — about 15 minutes from most of Frisco. Ground floor with free patient parking at the door.
The first visit is a full glaucoma evaluation — OCT, visual field, gonioscopy, pressure check, and records review. Plan on about 90 minutes. Bring your current medication list, prior testing, and insurance card. If MIGS is appropriate and cataract surgery is also planned, both can often be combined in a single session.
Open Monday–Friday 8:00–5:00 and Saturday 9:00–3:00, with English- and Spanish-speaking staff. Questions before booking? Call 214-972-2020 and a human answers.
06/FAQ
Questions patients ask, answered straight.
Don't see your question? Call 214-972-2020 or book a visit and ask Dr. Shehz directly.
Can Frisco patients get MIGS glaucoma surgery in Plano?
Yes. Frisco is one of our most-referred glaucoma service areas. The drive is about 15 minutes south on the Tollway. Dr. Shehz performs the evaluation, chooses the device, and handles all follow-up personally.
Is MIGS always combined with cataract surgery?
Often, but not always. iStent and Hydrus are commonly placed during cataract surgery for appropriate mild-to-moderate open-angle glaucoma patients. Goniotomy and canaloplasty can be standalone. Durysta and iDose are medication-delivery options that don't require cataract surgery. The combination depends on your cataract status, angle anatomy, and pressure goal.
Can MIGS replace my daily glaucoma drops?
Some patients reduce or eliminate drops after MIGS, but it's not guaranteed. The plan depends on your optic nerve status, pressure history, target IOP, and which device is placed. Dr. Shehz will set realistic expectations based on your specific testing before you commit to surgery.
How do I transfer my glaucoma records from my Frisco eye doctor?
Our team handles it. We send the records release directly to your Frisco optometrist or ophthalmologist and coordinate the transfer of OCT scans, visual fields, pressure logs, and medication history. Most transfers complete within a few business days.
What if my glaucoma is too advanced for MIGS?
Dr. Shehz will tell you directly. Advanced glaucoma with very low target pressures or significant progression may require trabeculectomy, tube shunt, or referral to a glaucoma sub-specialist. You'll never be pushed toward a MIGS device that isn't appropriate for your disease stage.
Does insurance cover MIGS surgery?
MIGS performed with medically necessary cataract surgery is typically covered by Medicare and most commercial insurance. Standalone MIGS or sustained-release implants like Durysta may have different coverage rules. We verify your benefits and provide a written cost estimate before scheduling.
How many trips from Frisco will I need for MIGS?
Typically three to five: the initial evaluation, a pre-op visit, surgery day, and one or two post-operative pressure checks. If MIGS is combined with cataract surgery, the schedule overlaps. Later pressure monitoring can often be coordinated with your Frisco optometrist.
Still have questions?
Talk to our team, no pressure, no sales pitch. We answer the question, not the upsell.
Cataracts in the picture too? MIGS and cataract surgery often happen together.
For many glaucoma patients, MIGS makes the most sense when cataract surgery is already planned. Dr. Shehz performs both in a single session — one anesthesia, one recovery, and a pressure-lowering device placed while the eye is already open.
Ready to talk pressure goals? The drive from Frisco is the easy part.
Book a glaucoma consultation, bring your records and medication list, and get a written pressure-lowering plan before choosing a device. About 15 minutes south on the Tollway. Call 214-972-2020 or book online.
