LASEK/PRK - Augenlasern ohne Schnitt

Summary

The script introduces the first generation of eye laser correction, known as KAKA, contrasting it with the newer LASIK and SMILE techniques. Unlike the latter, KAKA corrects vision directly on the corneal surface. The procedure involves dissolving and removing the epithelium with alcohol, followed by the excimer laser sculpting a precise curvature into the corneal tissue to correct refractive errors. A protective lens is then placed over the eye until the epithelium regenerates, a process that takes just a few hours.

Takeaways

• 👀 Kaka is the first generation of eye laser correction, distinct from the newer LASIK and SMILE procedures.
• 🔬 The correction of vision errors in Kaka is performed directly on the corneal surface.
• 🍸 The epithelium, the top layer of the cornea, is dissolved with alcohol in the initial step of the Kaka procedure.
• 🚫 After dissolving, the epithelium is removed to prepare the cornea for the laser treatment.
• ⚡ An excimer laser is used to model an accurately calculated curvature into the corneal tissue in a matter of seconds.
• 🔍 The laser treatment corrects the existing vision errors by reshaping the cornea.
• 🛡️ A protective lens is placed over the eye after the laser treatment.
• ⏱️ The healing process where the epithelium regenerates is relatively quick, happening within a few hours.
• 🎶 Background music is present throughout the explanation, suggesting a calm and informative tone.
• 🌐 The script is in German, providing information about the Kaka eye correction process in a non-English context.
• 📚 The transcript is likely part of an educational or informational video about eye laser correction techniques.

Q & A

What is the main difference between PRK (Photorefractive Keratectomy) and LASIK or SMILE?

PRK is an older generation of eye laser correction, where the correction of the refractive error is performed directly on the corneal surface, unlike LASIK and SMILE, which involve creating a flap in the cornea.

How is the epithelium, the outermost layer of the cornea, treated before the PRK procedure begins?

The epithelium is dissolved using alcohol and then removed to prepare the cornea for the laser treatment.

What does the excimer laser do during the PRK procedure?

The excimer laser is used to model an accurately calculated curvature into the corneal tissue within a few seconds to correct the existing refractive error.

What is the purpose of placing a protective lens on the eye after the PRK procedure?

The protective lens is placed to shield the eye until the epithelium, the top layer of the cornea, has regenerated.

How long does it typically take for the epithelium to regenerate after the PRK procedure?

The epithelium usually regenerates within a few hours after the procedure.

Is PRK a painless procedure?

The script does not specify the pain level during the PRK procedure, but it is generally known that there can be discomfort and pain after the procedure as the epithelium heals.

What is the role of alcohol in the PRK eye correction process?

Alcohol is used to dissolve the epithelium, the top layer of the cornea, before it is removed to allow the laser to correct the refractive error.

What happens to the eye during the excimer laser treatment in PRK?

During the excimer laser treatment, the laser reshapes the cornea by removing tissue to correct the refractive error, which is a process that takes only a few seconds.

Is there a recovery period after the PRK procedure?

Yes, there is a recovery period during which the epithelium regenerates and the protective lens is worn to protect the eye.

What type of music is included in the video script?

The script mentions music playing, but it does not specify the genre or style of the music.

What precautions should be taken after the PRK procedure to ensure proper healing?

The script does not detail specific precautions, but generally, patients are advised to avoid rubbing their eyes, follow post-operative care instructions, and attend follow-up appointments.
