Beyond 20/20: An Ophthalmologist's Guide to Eye Health and Surgery

Send us a text

Ophthalmic surgeon Dr. Micheál O'Rourke takes us through the fascinating world of eye health, sharing insights from cataracts and macular degeneration to aesthetic procedures and vision preservation.

• Eyes constantly move and blink even during sleep, requiring high energy and thin skin for optimal function
• Cataracts are an inevitable part of aging, involving protein misalignment in the lens requiring surgical removal and prosthetic lens replacement
• Macular degeneration comes in dry (less treatable) and wet (treatable with injections) forms that affect central vision but preserve peripheral sight
• Blepharoplasty (eyelid surgery) is becoming popular at younger ages, removing excess skin around the eyes for a refreshed appearance
• Women experience a dramatic drop in tear production during menopause, making HRT one of the most effective treatments for menopausal dry eye
• Increased screen time reduces our blink rate and contributes to vision problems including the evolutionary shift toward myopia in children
• Thyroid eye disease primarily affects young women, causing protruding eyes and altered appearance that can be addressed with surgery
• Eye floaters result from changes in the eye's jelly-like vitreous humor and should be evaluated if they suddenly increase or appear with flashing lights
• The eye cannot be temporarily removed during surgery as once believed, as nerve tissue damage is permanent

For more eye health insights, follow proper eye protection practices, get regular check-ups, and be aware of symptoms that might indicate serious conditions.
