Summary
Upper eyelid blepharoplasty slightly alters intraocular lens power calculations, though not to a clinically significant degree. Corneal topography measurements using Galilei showed no significant changes after the procedure.
Area of Science:
- Ophthalmology
- Corneal topography
- Refractive surgery
Background:
- Upper eyelid blepharoplasty is a common cosmetic procedure.
- Changes in corneal topography can affect intraocular lens (IOL) power calculations.
- The impact of blepharoplasty on precise refractive outcomes requires investigation.
Purpose of the Study:
- To evaluate the effect of upper blepharoplasty on corneal topography.
- To assess the impact of upper blepharoplasty on intraocular lens power calculations.
- To compare measurements obtained from Galilei and IOLMaster devices.
Main Methods:
- Observational case series of 30 patients undergoing upper blepharoplasty.
- Corneal topography and IOL power calculations performed using Galilei and IOLMaster preoperatively and at 1 and 6 months postoperatively.
- Vectorial analysis and paired t-tests used for statistical evaluation.
Main Results:
- Blepharoplasty induced minor corneal astigmatism (0.39 D with Galilei, 0.31 D with IOLMaster) 6 months post-surgery.
- IOLMaster showed statistically significant increases in corneal curvature and astigmatism post-surgery.
- IOLMaster indicated a significant decrease in IOL power 6 months after surgery.
Conclusions:
- Upper eyelid blepharoplasty has a statistically significant but not clinically significant influence on IOL power calculations via IOLMaster.
- No significant corneal topographic changes were detected using the Galilei device following blepharoplasty.

01:16Focusing of Light in the Eye
4.1K
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...

01:25Glaucoma: Overview
1.1K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:27Open Angle Glaucoma: Treatment
831
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.

01:28Angle Closure Glaucoma: Treatment
955
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...
