OLCI measures segmented AL
PCI does not
miserable communication !
SSOCT measures the best
If all panelists could say which IOL formula they use for outlayer measurements as Dr Peyman mentioned.
It differs for regular and VIP cases
Kane and Barret Universal 2, olsen and OKULIX by OA2000 are my favorite ones.
For RLE, I add online calculators like Barret and HofferQST + HillRBF
in KC cases I did not have good results with okulix OA2000
For regular cases even if outlier I use Olsen+Haigis+Okulix
I have the best experience with kane
Okulix is not specially designed for KC, and there might be error in defining the radii, you might add about 30-50 % of the keratometric astig to the calculated power for better result
Exactly or use Kane as Sasan mentioned
The Okulix TORIC calculator is excellent in mild KCN
the model fit for cornea is somewhat more efficient in Okulix toric, using the eccentricity of the cornea
And TMS-5 or Casia-2
The printout of the TMS-5 and Casia-2 okulix is not a good-looking one, I still prefer OA2000
In Okulix for TMS or CASIA posterior corneal power is included but not in OA2000
So TMS and CASIA may be preferable in KC and post ref?
The OA is specially designed for this, theoretically the TMS5 should have better result, but painful to calculate in the software
They should improve the display quality for Casia and TMS5 workstations.
The good point for TMS 5 is that it is pretty easy to update the IOL database in the windows software.
I need VPN to enter the https://iolsolver.com/ you were right dear Hesam
Thank you Alireza for usefull comments
Future of IOL calculation in KC and post ref is exact K measurements. TK IOL master or TCRP Pentacam AXL
Esp in toric
In theory the AI adjustment on Ray-tracing + accurate measurements will have the best result, still no formula with all this characterstics
Any slide to display?
Good points.The most catastrophic calculation is Toric calculation in post LVC ectasia cases.
An important issue regarding IOL calculation in KCN cases is the astigmatic refracive effect of coma that could not cover with TCP.
I've written a letter on Haigis-L theoretical error
Dr Eslampour you mentioned in KC cases astigmatic refracive effect of coma not cover with TCP. I agree . but we have no other formula to include coma or refractive astigmatism in IOL power or IOL toricity.
The only way is to compare astigmatism of cornea and refraction and if the difference is not high the error may be acceptable.
It is not possible to calculate the internal astigmatism in the presence of cataract
Exactly. Reinstein has a new theory of considering MRC(Manifest refractive cylinder) versus TCP in these cases.
Even a tiny PSC will make deviations of measurement significantly
if we can do refraction . it helps. otherwise just compare central and peripheral cylinder. In advance KC toric IOL results is prone to error
Although we the lenticular astigmatism component would be double treated.
Don't forget Fourier analysis to find the regular component of the astigmatism
do anyone have master 700 upgrade for TK?
He has showed that the amount of double treated lenticular astimatism is less than residual coma and its indused astigmatism.
Not available in our hospital
Holladay 2 is not good at all
ممنون استاد قریشی
can we put Galilei TK in IOL calc formula to calculate spherical power of IOL?
I agree with you Dear Alireza.
Least error after RK with Olsen, and Haigis, they use direct measurement of ACD for ELP estimation
But I legally use the ASCRS calculator
OLSEN is available in pentacam AXL
