Which of the following is NOT a common reason for ocular surgery?

Improving sleeping patterns is not a common reason for ocular surgery. Surgical interventions in ophthalmology typically focus on addressing specific eye conditions that can lead to vision impairment or other ocular health issues.

Cataract removal is a well-established procedure to restore vision affected by clouded lenses. Degenerative retinal diseases, such as age-related macular degeneration or diabetic retinopathy, often require surgical or laser interventions to prevent further vision loss. Similarly, procedures to address refractive errors—like LASIK or PRK—are aimed at correcting vision to reduce dependency on glasses or contact lenses.

On the other hand, ocular surgery is not indicated for improving sleeping patterns. While some eye conditions might indirectly affect sleep quality (for instance, due to discomfort or pain), the primary focus of ocular surgical interventions is not related to sleep. Therefore, this option stands out as not fitting the typical reasons for undergoing ocular surgery.
