How should Dato-DXd be managed in the absence of necessary resources for ocular exams and referrals?
We typically send patients for baseline slit-lamp exams prior to the start of Dato-DXd. If these resources are not available, telemedicine with slit-lamp biomicroscopic photography, as well as community screening resources, can be considered. Patients should still be educated on symptoms that would ...
How do you approach cataract surgery in a patient with a history of radial keratotomy (RK) who desires postoperative independence from glasses?
Carefully. I would say I'm abrupt and dispel the notion they will be spectacle independent at all, given they are not candidates for MTF lenses and, even EDoF lenses, would have issues of aberrations in the visual system caused by the RK incisions. I literally hang the "black drape." That sort of sh...
How do you decide the threshold and duration of subretinal fluid that can be safely tolerated in exudative AMD when adjusting treat-and-extend intervals?
There are so many other factors at play here. The very nature of this question begs the question of whether you are treating the patient or the OCT. Sadly, it appears the preponderance of patients I have seen are treated at fixed intervals of 1-2 months and no treat and extend, even from physicians ...
For patients with nAMD who are developing GA in the same eye, do you consider adding anti-complement therapy?
My personal perspective, shared by many colleagues around the country, is that the minimal anatomic and functional benefit of anti-complement therapy does not outweigh the aggregate risks and costs of perpetual treatment with these agents. I discuss these issues with my GA patients (including those ...
For very low cylinder that does not qualify for a toric lens and no access to femto, do you ever consider LRIs or slightly adjusting your main wound placement (if possible)?
I personally don't do manual LRIs as they can be somewhat unpredictable. Adjusting the main wound to the steep axis can treat 0.1 to 0.3 D due to SIA, so that might be the safest plan if femto is not available. B&L's Envista toric does treat as low as 1.25D, so that may also be an option.
When do you consider performing laser refractive surgery on corneal transplants?
This can be somewhat dependent on the tools you have available. In general, if the astigmatism is regular after a corneal transplant, depending on the corneal thickness and overall refractive error, you can consider photorefractive keratectomy in a transplantation patient. If the astigmatism is irre...
What is your approach to offering PRK for 1 diopter of myopia in patients over 45 with a corneal thickness of 450 microns and no keratoconus?
I am not sure why you would treat this patient?. One diopter of myopia over 45 years old. The patient probably has pretty good reading and distance vision without glasses. What is the patient’s visual goal? They want 20/20 distance without correction and now lose all ability to read?
Who are good candidates for light adjustable lenses?
Ideal Candidates Desire for spectacle independence, especially those motivated to fine-tune vision after surgery. High expectations for visual precision — e.g., engineers, pilots, or patients highly sensitive to small refractive errors. Previous refractive surgery (LASIK, PRK, RK)** — where IOL pow...
How do you adjust postoperative refraction targets for LAL in patients with altered corneal anatomy?
I don't adjust any postoperative refraction targets based on prior refractive surgery or previous EK, but modify the approach to adjustments. In patients with a history of PRK/LASIK, we wait at least 6 weeks to initiate adjustments. In patients with a history of RK, we wait 8+ weeks to start adjustm...
In patients with early Fuchs’ endothelial dystrophy, how do you determine whether to proceed with cataract surgery alone versus a combined endothelial keratoplasty?
If Corneal thickness is >640 or specular microscopy is lower than 1,000, those are indicative of poor outcome after cataract surgery and patients may benefit from combined procedure. However, some patients with Fuchs can be misleading as having a low corneal thickness but a dense central guttae that...
