Summary
This study shows that hyperopic laser in situ keratomileusis (LASIK) is a safe and effective method for correcting hyperopia, even after previous refractive surgeries.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Surgery
Background:
- Hyperopic LASIK offers a potential solution for correcting farsightedness.
- Previous refractive procedures can complicate subsequent surgical interventions.
Purpose of the Study:
- To evaluate the safety and efficacy of hyperopic LASIK using a 6.0 mm optical zone.
- To assess outcomes in patients with diverse prior refractive surgery histories.
Main Methods:
- 14 eyes of 14 patients underwent hyperopic LASIK with a VISX Star laser.
- Patients had a history of radial keratotomy, automated lamellar keratectomy, or prior LASIK.
- A toroidal ablation pattern was created using a novel blocking technique.
Main Results:
- Mean preoperative hyperopia was +1.33 D, reduced to -0.15 D postoperatively.
- 93% of eyes achieved uncorrected visual acuity of 20/40 or better.
- No significant complications were observed, though four eyes required enhancement for myopia.
Conclusions:
- Hyperopic LASIK with this technique is safe, predictable, and stable.
- This method provides a straightforward approach to adding hyperopic correction.
- It is a viable option for patients with prior refractive surgery.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
