    Area of Science:

    • Ophthalmology
    • Surgical Techniques

    Background:

    • Cataract surgery aims for effective lens removal with minimal complications.
    • Conventional methods may carry risks such as vitreous loss and induced astigmatism.

    Purpose of the Study:

    • To evaluate the efficacy and safety of lensectomy as a new technique for lens extraction.
    • To identify specific cataract types where lensectomy offers advantages over traditional approaches.

    Main Methods:

    • Lensectomy involves cutting and aspirating lens material through a fine-bore needle.
    • Instruments typically used for vitreous surgery were employed.
    • The technique was applied to seventy eyes for cataract removal.

    Main Results:

    • Lensectomy is a simple and atraumatic procedure.

  • The small limbal incision requires no sutures, reducing vitreous loss and astigmatism.
  • The technique is particularly advantageous for cataracts secondary to uveitis, as well as traumatic, presenile, and congenital/juvenile cataracts.

    • Conclusions:

    • Lensectomy presents a valuable alternative for specific cataract cases.
    • It is not suitable for calcified or hard-nuclei cataracts.
    • Potential complications include endothelial damage, vitreous seeding, and retinal detachment.
