The imagined patients are 18-45, have no other eye pathologies and are in good health:

Note: This is not peer-reviewed, has not been prepared by actual doctors or researchers, and is simply posted as an informal starting guide for anyone considering surgery for their floaters. This is not actual medical advice and should not be construed as anything other than imagined conversation between two imaginary surgeons. Their opinions are biased by their own beliefs and approach. Also, as they are not actual doctors, errors are likely.

Dr. Limited: "I still think we're doing more vitrectomy than we need to in many young patients. If I've got an otherwise healthy 25- or 35-year-old with a localized macular problem, why am I inducing a posterior vitreous detachment (PVD) and removing pristine vitreous that's been attached since birth?"

Dr. Complete: "Because if you leave attached vitreous behind, you've also left the substrate for future traction. The surgery may go perfectly today, but residual cortical vitreous can contract months or years later. I'd rather deal with that once than have the patient come back needing another operation."

Dr. Limited: "That's assuming the residual vitreous becomes a problem. In young patients, the vitreous is structurally normal. Most of them would never develop pathological traction if we hadn't disturbed it in the first place. Inducing a PVD creates an artificial event decades earlier than nature intended."

Dr. Complete: "True, but surgery itself changes the eye. Once you've entered the vitreous cavity, you're no longer dealing with a completely natural environment. If I'm already there, I want to eliminate as many tractional forces as possible."

Dr. Limited: "At what cost? PVD induction in a 20- or 30-year-old can be difficult. The vitreoretinal adhesion is much stronger than in a 70-year-old. Every attempt to peel that hyaloid increases the chance of creating retinal breaks."

Dr. Complete: "Only if it's done aggressively. Modern aspiration techniques, visualization with triamcinolone, and careful elevation of the posterior hyaloid have made it considerably safer. And I'd argue that postoperative retinal tears from residual traction are also a real concern."

Dr. Limited: "But the intraoperative risk is immediate and unavoidable. You're applying traction to a retina that wasn't detached to begin with. Why manufacture that risk?"

Dr. Complete: "Because incomplete surgery carries its own risks. Consider recurrent epiretinal membrane formation. Residual cortical vitreous provides a scaffold for cellular proliferation."

Dr. Limited: "Yes, but recurrence rates after membrane peeling are already fairly low, especially if the internal limiting membrane (ILM) is peeled. The evidence that complete vitrectomy dramatically lowers recurrence isn't overwhelming."

Dr. Complete: "Fair point. But it's not just membranes. If there are subtle peripheral vitreoretinal adhesions, I'd rather know they're relieved than wonder whether they'll become symptomatic later."

Dr. Limited: "Except the peripheral vitreous is doing useful things. It stabilizes the vitreous gel, contributes to normal biomechanics, and probably slows oxygen diffusion. The more vitreous you remove, the more you alter the intraocular environment."

Dr. Complete: "That's mostly a cataract argument, and we're talking about younger phakic patients. Yes, increased oxygen exposure after vitrectomy accelerates nuclear sclerosis. But if surgery is indicated, visual rehabilitation usually outweighs the possibility of needing cataract surgery years later."

Dr. Limited: "Years? Sometimes it's much sooner, especially after a complete vitrectomy. Preserving anterior and peripheral vitreous may delay cataract progression."

Dr. Complete: "Maybe. But the data are mixed, particularly when comparing limited versus complete vitrectomy rather than vitrectomy versus no vitrectomy."

Dr. Limited: "Another issue is operative efficiency. Limited vitrectomy often means less surgical time, less instrument manipulation, and potentially less postoperative inflammation."

Dr. Complete: "Maybe fifteen minutes saved today, but if even a small percentage require reoperation, have we really gained efficiency?"

Dr. Limited: "Most don't."

Dr. Complete: "Most also tolerate complete vitrectomy very well."

Dr. Limited: "Let's talk retinal tears. Young attached vitreous is notorious. Every retinal surgeon has had that moment where the hyaloid suddenly releases peripherally and creates a break."

Dr. Complete: "And every retinal surgeon has also seen delayed tears from persistent vitreous traction after an incomplete procedure."

Dr. Limited: "Those aren't equivalent risks. One is induced by the surgeon; the other is a possible future event."

Dr. Complete: "Patients don't care whether the complication happens today or next year. They care whether it happens."

Dr. Limited: "Fair enough. But patients also value preserving normal anatomy whenever possible. My philosophy is to treat only what's causing the problem."

Dr. Complete: "Mine is to treat the entire mechanical system responsible for the disease."

Dr. Limited: "I think you're extrapolating from older patients, where spontaneous PVD has already occurred or is imminent."

Dr. Complete: "And I think you're underestimating how much surgery itself changes vitreoretinal dynamics."

Dr. Limited: "Suppose it's a healthy 28-year-old with a focal vitreomacular traction. I'd release the traction, remove only what's necessary, leave the remaining attached vitreous alone, and stop."

Dr. Complete: "I'd induce a complete PVD, perform a thorough core and posterior vitrectomy, inspect the periphery carefully with scleral depression, treat any breaks I find, and know the traction has been comprehensively eliminated."

Dr. Limited: "You're accepting greater operative complexity for theoretical long-term benefits."

Dr. Complete: "And you're accepting possible future pathology to preserve tissue that may no longer be beneficial after surgery."

Dr. Limited: "Perhaps the real answer is that surgery should be proportional to the disease."

Dr. Complete: "On that, we probably agree. If the pathology is highly localized and the risks of PVD induction are substantial, restraint has merit. If traction is diffuse, visualization is poor, or there's concern about residual vitreous causing recurrence, a complete vitrectomy becomes much easier to justify."

Summary:

Where the strongest arguments lie:

Arguments favoring a limited vitrectomy:

-Preserves more native vitreous and ocular biomechanics.

-Avoids technically challenging PVD induction in young eyes with strong vitreoretinal adhesion.

-May reduce the risk of iatrogenic retinal tears during surgery.

• May shorten operative time and decrease surgical manipulation.

-Could theoretically slow cataract progression by retaining more vitreous.

Arguments favoring a full vitrectomy with PVD induction:

-Eliminates persistent vitreoretinal traction.

-May reduce the chance of recurrent tractional disease or the need for repeat surgery in selected cases.

-Provides more complete visualization and treatment of the retina.

-Leaves less residual cortical vitreous that could serve as a scaffold for future pathology.

-Establishes a more predictable postoperative vitreoretinal state.

In contemporary vitreoretinal surgery, both philosophies are represented among highly experienced surgeons. Many surgeons now individualize the extent of vitrectomy based on the patient's age, the underlying disease, the strength of vitreoretinal adhesion, and the balance between immediate surgical risk and long-term anatomic stability. There is no universal consensus that a complete PVD should always be induced in every healthy young patient undergoing pars plana vitrectomy.

Editor's note: I underwent two full vitrectomies, but that was after natural PVDs so no induction was required. Further, those surgeries were done to peel epiretinal membranes/macular puckers. The floater removal was a secondary effect of those.

For example, if a treatment offered a 20% improvement in your floaters, would that be worth your consideration?

How about 50%, 75%, 85%, 99% or anything in between.

Assume for the purpose of this exercise that there are risks in any potential procedure, and that the costs are managable and within similar ranges.

There are no right or wrong answers here.

Obviously this is purely hypothetical and just something to get a sense of the collective burden floaters present to you and at what level of improvement you would feel a significant quality of life change.
