Abstract: Lid surgery plays a crucial role in the management of various ophthalmic conditions, ranging from cosmetic enhancements to functional improvements and therapeutic interventions. This article provides an extensive review of lid surgery, exploring traditional techniques, minimally invasive procedures, and recent innovations. By examining the latest advancements in lid surgery, ophthalmologists can enhance their understanding and improve patient outcomes.

Introduction: The eyelids are essential structures that protect the eye, distribute tear film, and contribute to facial aesthetics. Lid surgery encompasses a wide range of procedures aimed at addressing lid malpositions, ptosis, entropion, ectropion, tumors, and cosmetic concerns.

Traditional Lid Surgery Techniques:

1. Ptosis Repair: Ptosis surgery involves elevating the upper eyelid to improve visual function and aesthetics.

2. Entropion and Ectropion Repair: Surgical correction of entropion (inward turning of the eyelid) and ectropion (outward turning of the eyelid) restores lid position and function.

Minimally Invasive Lid Surgery Techniques:

1. Botulinum Toxin (Botox) Injection: Botox injection for blepharospasm, hemifacial spasm, and cosmetic purposes offers a minimally invasive approach to address lid-related concerns.

Recent Innovations:

1. Microneedling: Microneedling with or without radiofrequency energy offers a non-surgical approach to treat periorbital wrinkles, laxity, and skin texture irregularities.
   • DermNet New Zealand provides insights into microneedling for periorbital rejuvenation: Microneedling for Periorbital Rejuvenation
2. Platelet-Rich Plasma (PRP) Therapy: PRP therapy promotes tissue regeneration and collagen production, offering potential benefits in eyelid rejuvenation and scar revision.

Conclusion: Lid surgery encompasses a wide range of procedures aimed at improving both functional and aesthetic aspects of the eyelids. By staying informed about the latest advancements in lid surgery, ophthalmologists can offer state-of-the-art care to patients, addressing their unique needs and enhancing overall quality of life.
