Visual Outcome in High Myopia After Laser in situ Keratomileusis

Area of Science:

• Ophthalmology
• Refractive Surgery

Background:

• Investigating the efficacy of Laser-Assisted In Situ Keratomileusis (LASIK) for correcting high myopia (>-12.00 D).
• Utilizing the Hansatome microkeratome and Nidek EC-5000 excimer laser for surgical procedures.

Discussion:

• Assessing visual acuity outcomes and comparing them to preoperative spectacle correction.
• Analyzing the extent of refractive correction and visual gain or loss post-LASIK.
• Evaluating the safety and complication profile of LASIK in this high myopia cohort.

Key Insights:

• 40% of eyes gained visual acuity lines, 56% remained unchanged, and 4% lost one line.
• 110 eyes achieved uncorrected visual acuity equal to their best spectacle-corrected visual acuity.
• Undercorrection was observed in 35 eyes, primarily within the -0 to -5.00 D range.

Outlook:

• LASIK with the Nidek EC-5000 excimer laser demonstrates favorable results for managing severe myopia.
• Further research could explore long-term outcomes and patient satisfaction in this demographic.
