Today we present a quick review of IOL selection and calculations when performing cataract surgery on patients with retinal disease. There are many considerations including refractive outcome, IOL design, optic type, and more. It goes without saying that we want to implant an acrylic IOL in patients where there is a chance that a future vitrectomy with silicone oil would be needed. There are some great pearls in the video and I know that you will pick up one or two to help in your own practice.

I recommend placing a capsular tension ring in cases of RP. Capsular support hooks could be helpful since zonular weakness is common in RP.
if I have a Lenstar, I am calculating for IOL in a silicone filled eye
I added info to calculate for silicone filled eye
do I used the SRK T formula numbers as printed?
the modification is already done for me?
the oil may be removed, but patient is monocular
so you never know
how to proceed in this 27.5 mm monocular SO filled eye?
what to aim for?
The patient is obviously myopic based on the axial length. My advice is to add about 4.5 diopters to the IOL power which gives you emmetropia. If the silicone oil stays in then the patient will be close to plano. If the oil is taken out in the future the patient will end up about -2.75 which is also a nice outcome.
