While these advances are promising, there are still some challenges that need to be addressed. For example, gene therapy is still in its early stages of development, and it is not yet clear how effective it will be for all eye diseases. AI is a powerful tool, but it is important to ensure that it is used ethically and responsibly. 3D printing is still a relatively new technology, and it is not yet clear how it will be used to create custom eyewear on a large scale. Stem cell therapy is also a new technology, and it is not yet clear how safe and effective it will be for eye diseases. Telemedicine is becoming more popular, but it is important to ensure that the quality of care is the same as if the patient were seeing an eye doctor in person.
