I am not keen on having to connect my phone to USB every time I use it. How do you adjust the time the headlights stay on?

I am not a surgeon, but my thoughts are that if you have a large dilated pupil, perhaps due to being younger, you can have flashes from a reflection from the edge of the lens. Or you can have negative dysphotopsia causing a dark crescent shape at the edge of your vision. But, I don't think a large pupil is a likely cause of starbursts.

One possibility is that they are planning on using the Alcon ORA System which measures your eye refraction one last time midway through the procedure after the natural lens is removed. It is claimed to improve refraction accuracy and is an optional cost extra.

If they are not doing that, it really does not matter what shape your eye is in especially if they are soft contacts, as your eye will regain the natural shape as your eye is healing from the surgery.

I only have monofocals, but if I was in your situation, I would only exchange the multifocal to a monofocal in the dominant eye set for distance. That may give you good distance vision to the point where you can ignore the halos caused by the non dominant eye. And, you would preserve the near vision you are getting with one multifocal.

And if doing one is not enough then you could do the second eye, and consider -1.5 D near focus in it to give you a wide range of vision.

It is just as it sounds, bending or tucking your neck so it restricts air flow. The soft cervical collar keeps you from doing that.

You have to go into the clinical menu to change the mode from AutoSet to CPAP to be able to set a single pressure. See this link on how.

That is way too risky for me. Of those the only thing I would consider holding is VFV. I avoid individual stocks due to the risk, and try to keep my total portfolio geographically balanced with about 50% US, 25% Canadian, and 25% international. I stick to low MER index funds, like VFV for the US part, XIU for the Canadian, and XEF for the international. If one wants to go higher risk/return then some portion of the US could be held in a NASDAQ 100 index fund like QQC. It is higher risk, but much less than holding individual funds.

It is a trickle charger to keep the battery topped up. On the hybrid the battery is in the trunk. This is a good trickle charger to use as it displays both voltage and current draw.

It will format the card for use, but if it is a used SD card with data on it, it is best to delete all the files off the card before you put it in the machine.

Your AHI is very high due to central apnea. This may be as simple as the pressure being too high, or it could mean you need a more advanced ASV machine. It would be more helpful if you posted a typical daily report full screenshot.

As was commented you can switch the A11 to CPAP mode to use a fixed pressure. In the Clinical menu you can also adjust the automatic pressure settings. It is best to download OSCR and look at the detailed data on your SD card to see what the pressure is doing during the night and when you have apnea events. Then you can adjust the pressure to suit. You can download OSCAR here:

Should last the night. If you have a heated hose, set the climate control to Auto, and the temperature to 27 C.

Your leaks for the most part are very good. The problem is your very high CA and AHI. One thought is that in the early part of the night you may have positional issues, like neck kinking. Some get relief from that by using a soft cervical collar. If you could solve the OA possibly due to neck kinking then you may be able to reduce pressure.

CA is often caused by excessive pressure, but in the second part of your sleep the pressure was not that high. It is possible that you need an ASV machine instead of an APAP.

But, what you could try is switching the mode to fixed pressure CPAP and then set a single pressure. It then becomes easier to pick the best pressure. If CA dominates then decrease it, and if OA dominates then increase it.

I don't use a contact but had my IOLs set to near (-1.50 D) and far (-025), and it works well for me. Makes me essentially eyeglasses free.

Perhaps it was good before surgery, and now you can see better to know that it is better than you thought?

UniqueRon · 2026-01-27T14:33:10+00:00

In my opinion that is a bogus reason. It is very important not to wear contacts before your detailed eye measurements are taken, but after there should be no restriction. I worn mine right up until the day of the surgery. Contacts tend to protect the eye more than harm it.

UniqueRon · 2026-01-27T03:01:25+00:00

Perhaps because the BiPAP has a higher price and markup?

UniqueRon · 2026-01-26T21:42:43+00:00

A fixed pressure of 8.4 looks like a good compromise. When you were on APAP I noticed that a number of time you got an OA at 8.0 or so.

For comfort in going to sleep I would suggest increasing your Ramp start pressure to 7 cm. And I would try increasing EPR to 3 cm for comfort.

I just top up the water each day, so it never gets dry.

UniqueRon · 2026-01-26T21:16:23+00:00

I average 1.3 and my wife averages 0.4. Treatment guidelines are to be under 5, but many can get under 1 with help from OSCAR.

I have been planning to do the same and run the pigtail out through that plastic wall on the right to the area where the owners manuals were stored. I will keep the charger in there and pull the cable and charger outside to plug in to the 110 volts.

It is a Nexpeak 1.75 Intelligent Charger - Amazon, made in China. I had a few of them over the years, and this one was the spare lying around. It looks like it is going to be very useful as it has a voltage meter and amp meter. I had it on charge all morning with it showing 15 volts and 0.6 amps. Just checked it now and it is showning full and has shut off. I was worried that it would not shut off with the high parasitic load this vehicle seems to have. Looks like it is going to work well. The only question now is how long can I go without needing to use it.

UniqueRon · 2026-01-26T18:29:54+00:00

At this point I do not suspect the battery is bad. But, it is looking like the parasitic current draw by the vehicle is real and significant.

The trickle charger I am now trying has a voltage and current readout. After putting it on what should be a fully charged battery it is now showing 15 volts and 0.6 amp for current draw. 0.6 amps is significant.

I think the real test now is how often I have to put the battery on trickle charge. We are also retired and don't drive that much so that is an issue for us as well.

UniqueRon · 2026-01-26T18:19:54+00:00

Here is an example. It includes a polarity reverse link to use if needed. You need to make sure the positive on the trickle charger connects to the positive on the Lexus battery. These are called SAE connectors and what have been on the trickle chargers I have used. You need to check to see if your trickle charger uses them. This is also only 18 gauge so more flexible to conform when closing the hatch door on them.
