There are military grade lenses that can be made better. However, it's not conceivable for consumer mass production. It's also more fragile in higher index, the lens would not sustain the test of impact for it to pass the safety standards to sell to consumers.
The higher the index, the more distortion outside the optical center of the lenses. However, you can get pretty good asperic lenses made in 1.74 for -10.00 and some astigmatism correction. They have some pretty good ones at Zeiss or Hoya lensmaker.
For those eyes, the other options would be LASIK, PRK, refractive lens exchange, contact lenses, RGP lenses, orthokeratology for full or partial correction to wear a less strong lens.
