Short-term 3D visual training enhanced accommodative amplitude and facility in both small incision lenticule extraction (SMILE) and implantable Collamer lens (ICL) patients. However, accommodative lag improved more significantly in the ICL group following training.
Area of Science:
- Ophthalmology
- Vision Science
- Refractive Surgery
Background:
- Refractive surgery, including small incision lenticule extraction (SMILE) and implantable Collamer lens (ICL) implantation, aims to correct myopia.
- Understanding the impact of these procedures on visual functions like accommodation is crucial for patient outcomes.
Purpose of the Study:
- To compare the short-term effects of autostereoscopic 3D visual training on accommodative responses in patients who have undergone SMILE versus ICL surgery.
- To evaluate changes in accommodative amplitude, facility, and lag after a standardized 3D training session.
Main Methods:
- A prospective study included 28 myopic patients (14 SMILE, 14 ICL) one month post-surgery.
- Participants underwent a 12-minute autostereoscopic 3D visual training session.
- Accommodative parameters were measured before and after training using the Grand Seiko WAM-5500.
Main Results:
- Both SMILE and ICL groups demonstrated significant improvements in accommodative amplitude and facility post-training.
- A significant interaction between surgical group and time was observed for accommodative lag.
- Accommodative lag decreased significantly more in the ICL group compared to the SMILE group post-training.
Conclusions:
- Short-term 3D visual training effectively enhances accommodative amplitude and facility in both SMILE and ICL patients.
- The ICL group exhibited a more pronounced reduction in accommodative lag compared to the SMILE group after 3D training.
- These findings suggest differential accommodative adaptations to visual training based on the type of refractive surgery.
