Summary
Phacoemulsification outcomes in eyes with extreme axial myopia were similar to general populations. Refractive results showed a hyperopic shift, particularly with negative-power intraocular lenses.
Area of Science:
- Ophthalmology
- Surgical Outcomes
- Biometry
Background:
- Extreme axial myopia presents unique challenges for cataract surgery.
- Understanding surgical outcomes is crucial for managing these complex cases.
Purpose of the Study:
- To evaluate the outcomes of phacoemulsification in eyes with extreme axial myopia (axial length > 30.0 mm).
- To assess complications and refractive results following cataract surgery in this specific patient group.
Main Methods:
- Retrospective analysis of a consecutive case series of eyes with extreme axial myopia undergoing phacoemulsification.
- Data collected included surgical details, intraoperative complications, and postoperative refractive outcomes.
- Incidence of postoperative retinal detachment was assessed in a subgroup without prior retinal detachment or vitrectomy.
Main Results:
- 177 eyes were analyzed; intraoperative complications were infrequent (e.g., posterior capsule tear 2.8%).
- Postoperative retinal detachment occurred in 1.3% of eyes without prior history.
- Median biometry prediction error was 0.88 D, with higher error in eyes receiving negative-power intraocular lenses (IOLs).
Conclusions:
- Phacoemulsification in extreme axial myopia has complication rates comparable to unselected populations.
- A hyperopic refractive shift was observed, influenced by axial length and the type of IOL used, especially negative-power IOLs.

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...
01:25Glaucoma: Overview
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
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.

01:23Ophthalmic Drug Delivery Systems
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
