Summary
Combining multifocal lens implants with laser eye surgery (bioptics) effectively corrects residual refractive errors without compromising visual function. This approach offers superior outcomes compared to multifocal lenses alone.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Surgery
Background:
- Achieving precise postoperative emmetropia is crucial for optimal outcomes with multifocal intraocular lenses (IOLs).
- Bioptics, combining IOL implantation with refractive surgery, can correct residual refractive errors but raises concerns about visual side effects.
Purpose of the Study:
- To evaluate the functional outcomes of combining laser subepithelial keratomileusis (LASEK) with multifocal IOL implantation.
- To assess potential declines in contrast sensitivity, low-contrast visual acuity, glare visual acuity, and night-driving simulation after bioptics.
Main Methods:
- LASEK was performed on eight eyes of seven patients following multifocal IOL implantation.
- Visual acuity, contrast sensitivity, low-contrast visual acuity, glare visual acuity, and night-driving simulation were assessed preoperatively and 6 months postoperatively.
Main Results:
- Postoperative contrast sensitivity and low-contrast visual acuity showed non-significant improvements.
- Glare visual acuity improved significantly, with measurements increasing from 12.5-50% to 28.5-57%.
- Night-driving simulation results remained stable, with four patients meeting strict criteria.
Conclusions:
- Bioptics, combining multifocal IOLs with LASEK, effectively minimizes postoperative ametropia without negatively impacting visual function.
- This combined approach appears to offer superior results compared to exclusive multifocal IOL implantation.

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...
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...
01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
