井上眼科病院における多焦点眼内レンズ挿入術対象者の推移

Trends of multifocal intraocular lens implantation at Inouye Eye Hospital

要約　目的：井上眼科病院における自費診療と先進医療の多焦点眼内レンズ（IOL）挿入術対象者の推移を後ろ向きに調査した。

対象と方法：対象は，2014年9月〜2016年12月に井上眼科病院で，多焦点IOL挿入術を施行した353例548眼（自費診療163例264眼，先進医療190例284眼）である。2016年1〜12月に当院で施行した単焦点IOL挿入例（10歳未満を除く）3,719例5,127眼を比較対象とした。

結果：多焦点IOL挿入術は，2009年以降，徐々に増加した。自費診療と先進医療の割合は同等であった。多焦点IOL挿入例は女性の割合が多く，単焦点IOL挿入例より平均年齢は若かった。自費診療と先進医療では，先進医療保険加入の状況，職業，多焦点IOLの情報源について異なる傾向を示したが，多焦点IOLの情報源については，いずれも医療機関を受診した際が最も多かった。

結論：多焦点IOLは，若い年齢層が多く，情報源については，いずれも医療機関を受診した際が最も多かった。

Abstract　Purpose：To present a review of patients who received cataract surgery with implantation of multifocal intraocular lens（IOP）in the past 28 months.

Cases and Method：This study was made on 548 eyes of 353 cases who received cataract surgery with implantation of multifocal intraocular lens（IOP）during 28 months through December 2016. The medical expenses were not covered by public insurance in 264 eyes of 163 cases, and were covered as advanced medical care in 284 eyes of 190 cases. The findings were compared with 5,127 eyes of 3,719 cases who received implantation of conventional monofocal IOL during 2016.

Results：There was a gradual increase in the number of cases who received implantation of multifocal IOL since 2009. The ratio of non-coverage by insurance versus advanced medical care remained fairly constant. There were more women than men who chose multifocal IOL. Those who chose multifocal IOL tended to be younger in age than monofocal IOL. Information about multifocal IOL was generally supplied at medical clinics.

Conclusion：Implantation of multifocal IOL was preferred by younger generation. Information over multifocal IOL was most frequently supplied at medical clinics.
