Medical science has come a long way in the last century, but human beings often seem to come up with yet more physical debilities that need correction. While medical professionals today have many useful tools to correct or alleviate issues, cures for many diseases are not yet available. The world of science is charged with the task of learning how things happen and correct them, and scientists are still looking for advances that can make life better. It might appear they are only searching for ways to create profit, but many of them have concerns for the health of their fellow man.
There are many vision issues today that can be corrected with procedures that have been perfected over the years, and cataracts are one of them. People who used to get them would eventually go blind, but surgical procedures today only take a few minutes to give the patient relief and clear vision. Being able to see again might seem like a miracle, but it is due largely to the tedious work of scientists obsessed with creating a better life for those around them.
Healthy eyesight is a blessing that is often taken for granted, but scientists are still seeking ways to help those who have lost it. They are unable to replace an entire eye as of yet, but there are other issues they have developed ways to fix. A person with bad eyesight due to astigmatism can now have it corrected by a medical laser procedure. Perfect vision has been achieved for some, but others have further issues that require more work.
The ability to see the world is one that people can survive if they lose it, but they are also losing a part of their enjoyment in life. For those with issues that have yet to be corrected through medical advances, hope is always on the horizon.
