Summary

TLDRLASIK is an outpatient surgical procedure to reduce dependency on glasses or contact lenses by reshaping the cornea. It involves numbing the eye, creating a corneal flap with a microkeratome, and using an Excimer laser to reshape the cornea. The procedure is quick, requires no stitches, and includes post-op care with antibiotic drops and an eye shield. Arrange transportation as driving is not advised immediately after.

Takeaways

👁️ LASIK is a surgical procedure to reduce dependency on glasses or contact lenses.
🌟 The acronym LASIK stands for Laser Assisted In Situ Keratomileusis.
🕒 The procedure typically takes about 15 minutes per eye.
💉 Topical eye drops are used to numb the eye before the procedure.
💊 A sedative may be given to help the patient relax.
🔄 A lid speculum is used to hold the eyelid open during the procedure.
🔧 A microkeratome is used to create a corneal flap by cutting a portion of the cornea.
⚡ The Excimer laser is used to reshape the cornea by vaporizing tiny portions of its interior.
🔄 The corneal flap is then replaced and observed for bonding.
🏥 No stitches are required as the cornea heals rapidly.
🚗 Arrangements for a ride home are necessary as driving is not recommended immediately after the procedure.

Q & A

What is LASIK and what does it aim to achieve?
-LASIK, which stands for laser assisted in situ keratomileusis, is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses by permanently changing the shape of the cornea.
How long does a LASIK procedure typically take?
-A LASIK procedure usually requires about 15 minutes per eye.
What is the role of the lid speculum in the LASIK procedure?
-The lid speculum is used to hold the eyelid open during the procedure.
What sensation might a patient experience when the suction ring is placed on the eye?
-Patients may feel pressure and experience dimming of their vision when the suction ring is placed on the eye.
What is a microkeratome and how is it used in LASIK surgery?
-A microkeratome is a special device that is attached to the suction ring and uses a blade to create a corneal flap by cutting approximately the outermost 20% of the cornea.
How does the Excimer laser contribute to reshaping the cornea during LASIK?
-The Excimer laser is used to reshape the cornea by vaporizing tiny portions of its interior, which usually takes less than 60 seconds.
Why does the cornea not require stitches after the procedure?
-The cornea bonds quickly after the procedure, which allows for rapid healing without the need for stitches.
What measures are taken to prevent infection after LASIK surgery?
-After the procedure, the doctor administers antibiotic drops to prevent infection.
Why is a protective shield placed over the eye after LASIK surgery?
-A protective shield is placed over the eye to prevent the patient from rubbing it or putting pressure on it while sleeping.
Why can't patients drive immediately after LASIK surgery?
-Patients cannot drive immediately following the procedure due to potential visual disturbances and the need for recovery.
What arrangements should be made for transportation after LASIK surgery?
-Patients should arrange for a ride home since they will not be able to drive immediately after the procedure.
