Acetazolamide at a dose of 250 mg every 8 hours. The next day, corneal edema had increased to grade III (Figure 2), with a wider unreactive pupil, with an IOP of 20 mmHg and no pain. A TASS was suspected, so she was instructed to use Prednisolone 1% every hour and keep on using the other medicines.
Anterior subcapsular cataract after TASS resolved.

Nevertheless, an anterior subcapsular cataract (Figure 3) and a fixed dilated pupil remained.
Specular microscopy of both eyes, showing a significant decrease in cell count and a clear increase in cell area in the right eye, while values remain normal in the left eye. Please also note the difference in pupil size between the right (UZS) and left (normal) eyes.

Specular microscopy confirmed an endothelial cell loss in the TASS eye, with a normal cell count in the contralateral eye (Figure 4).
Anterior segment densitometry (Pentacam) demonstrating a correctly implanted intraocular lens (IOL) with a proper vault over the crystalline lens. Anterior subcapsular cataract can also be seen.
