What does STEPHEN LEX research?
Dr. Lex studies the health impacts of conditions like type 2 diabetes and smoking on the eyes, specifically how they affect the cornea, which is the clear front part of the eye. He has researched how people aged 50 to 70 with both diabetes and a smoking habit experience greater harm to their corneal health compared to those with either condition alone. Additionally, he investigates how athletes, especially trained cyclists, can optimize their performance through strategic carbohydrate intake to enhance their muscle energy levels during competition and training.
Key findings
- Diabetic smokers showed the lowest average corneal cell density at 1,917 cells per square millimeter, significantly less than healthy nonsmokers and diabetic nonsmokers.
- In trained cyclists, muscle glycogen levels decreased by 34% after 3 days and 20% after 5 days following carbohydrate loading, indicating that high glycogen levels can be sustained for up to 5 days.
- The combination of diabetes and smoking was shown to have a more detrimental effect on corneal health than either condition on its own.
Frequently asked questions
- Does Dr. Lex study eye health?
- Yes, Dr. Lex studies how conditions like diabetes and smoking affect the health of the eye, particularly the cornea.
- What conditions does Dr. Lex focus on in his research?
- He focuses on the impacts of type 2 diabetes and smoking on eye health, as well as carbohydrate loading in athletes.
- How does Dr. Lex's work help athletes?
- His research helps athletes understand how to optimize their carbohydrate intake to maintain energy levels during training and competitions.
- Is Dr. Lex's research relevant for people with diabetes?
- Yes, his work highlights the increased risks to eye health for patients with diabetes, especially if they smoke.
- What is the importance of corneal health?
- Corneal health is crucial for clear vision and can be affected by conditions like diabetes and smoking, leading to potential vision problems.

Plain English
This study looked at how type 2 diabetes and smoking affect the health of the cornea, the clear front part of the eye, in 200 people aged 50 to 70. It found that diabetic smokers had the lowest average cell density in the cornea at 1,917 cells per square millimeter, which is significantly lower than both healthy nonsmokers and diabetic nonsmokers. This matters because the combination of diabetes and smoking is shown to harm the cornea more than either condition alone, potentially leading to eye problems.
Who this helps: This helps patients with diabetes who smoke by highlighting the increased risks to their eye health.
Supercompensated glycogen loads persist 5 days in resting trained cyclists.

Plain English
This study looked at how long trained cyclists could maintain high levels of muscle glycogen after a period of intense carbohydrate loading. Researchers found that after loading with carbs, glycogen levels in the muscles dropped by about 34% after 3 days, 20% after 5 days, and 46% after 7 days, indicating that glycogen can stay elevated for up to 5 days. This is important because it suggests that athletes can optimize their energy levels for training and competition by timing their carbohydrate intake effectively.
Who this helps: This benefits athletes, especially cyclists and endurance sports competitors.
